2. Pre-Defined Flows#

The following are examples are pre-built flows that come with SiliconCompiler which you can use for your own builds.

See the pre-built targets for examples on how these are used in conjunction with pdks, tools and libraries.

2.1. ASIC Flows#

Complete ASIC compilation flows that take RTL through synthesis, place-and-route, and finishing. The language argument selects the front-end used to bring the design into Verilog before the shared place-and-route back-end runs; a variant is shown below for each supported source language.

2.1.1. asicflow-verilog / 0#

A configurable ASIC compilation flow.

This flow targets ASIC designs, taking RTL through a complete synthesis, place-and-route, and finishing flow.

The flow is divided into the following major steps:

  • elaborate: RTL elaboration using Slang.

  • synthesis: RTL synthesis using Yosys.

  • floorplan: Floorplanning, including macro placement, tapcell/endcap insertion, power grid generation, and pin placement.

  • place: Global and detailed placement.

  • cts: Clock tree synthesis and post-CTS timing repair.

  • route: Global and detailed routing.

  • dfm: Design-for-manufacturing steps, primarily metal fill.

  • write: Writing out final views of the design (GDSII, etc.).

The synthesis, floorplan, place, cts, and route steps support parallel execution to explore different strategies. This can be configured by setting the corresponding *_np argument to a value greater than 1.

Args:
  • name (str, optional): The name of the flow. If not provided, it defaults to ‘asicflow-<language>’.

  • language (str): The hardware description language of the design. One of ‘verilog’, ‘systemverilog’, ‘systemverilog-sv2v’, ‘chisel’, ‘vhdl’, or ‘hls’.

  • syn_np (int): Number of parallel synthesis jobs to launch.

  • floorplan_np (int): Number of parallel floorplan jobs to launch.

  • place_np (int): Number of parallel placement jobs to launch.

  • cts_np (int): Number of parallel clock tree synthesis jobs to launch.

  • route_np (int): Number of parallel routing jobs to launch.

2.1.2. asicflow-systemverilog-sv2v / 1#

A configurable ASIC compilation flow.

This flow targets ASIC designs, taking RTL through a complete synthesis, place-and-route, and finishing flow.

The flow is divided into the following major steps:

  • elaborate: RTL elaboration using Slang.

  • synthesis: RTL synthesis using Yosys.

  • floorplan: Floorplanning, including macro placement, tapcell/endcap insertion, power grid generation, and pin placement.

  • place: Global and detailed placement.

  • cts: Clock tree synthesis and post-CTS timing repair.

  • route: Global and detailed routing.

  • dfm: Design-for-manufacturing steps, primarily metal fill.

  • write: Writing out final views of the design (GDSII, etc.).

The synthesis, floorplan, place, cts, and route steps support parallel execution to explore different strategies. This can be configured by setting the corresponding *_np argument to a value greater than 1.

Args:
  • name (str, optional): The name of the flow. If not provided, it defaults to ‘asicflow-<language>’.

  • language (str): The hardware description language of the design. One of ‘verilog’, ‘systemverilog’, ‘systemverilog-sv2v’, ‘chisel’, ‘vhdl’, or ‘hls’.

  • syn_np (int): Number of parallel synthesis jobs to launch.

  • floorplan_np (int): Number of parallel floorplan jobs to launch.

  • place_np (int): Number of parallel placement jobs to launch.

  • cts_np (int): Number of parallel clock tree synthesis jobs to launch.

  • route_np (int): Number of parallel routing jobs to launch.

2.1.3. asicflow-chisel / 2#

A configurable ASIC compilation flow.

This flow targets ASIC designs, taking RTL through a complete synthesis, place-and-route, and finishing flow.

The flow is divided into the following major steps:

  • elaborate: RTL elaboration using Slang.

  • synthesis: RTL synthesis using Yosys.

  • floorplan: Floorplanning, including macro placement, tapcell/endcap insertion, power grid generation, and pin placement.

  • place: Global and detailed placement.

  • cts: Clock tree synthesis and post-CTS timing repair.

  • route: Global and detailed routing.

  • dfm: Design-for-manufacturing steps, primarily metal fill.

  • write: Writing out final views of the design (GDSII, etc.).

The synthesis, floorplan, place, cts, and route steps support parallel execution to explore different strategies. This can be configured by setting the corresponding *_np argument to a value greater than 1.

Args:
  • name (str, optional): The name of the flow. If not provided, it defaults to ‘asicflow-<language>’.

  • language (str): The hardware description language of the design. One of ‘verilog’, ‘systemverilog’, ‘systemverilog-sv2v’, ‘chisel’, ‘vhdl’, or ‘hls’.

  • syn_np (int): Number of parallel synthesis jobs to launch.

  • floorplan_np (int): Number of parallel floorplan jobs to launch.

  • place_np (int): Number of parallel placement jobs to launch.

  • cts_np (int): Number of parallel clock tree synthesis jobs to launch.

  • route_np (int): Number of parallel routing jobs to launch.

2.1.4. asicflow-vhdl / 3#

A configurable ASIC compilation flow.

This flow targets ASIC designs, taking RTL through a complete synthesis, place-and-route, and finishing flow.

The flow is divided into the following major steps:

  • elaborate: RTL elaboration using Slang.

  • synthesis: RTL synthesis using Yosys.

  • floorplan: Floorplanning, including macro placement, tapcell/endcap insertion, power grid generation, and pin placement.

  • place: Global and detailed placement.

  • cts: Clock tree synthesis and post-CTS timing repair.

  • route: Global and detailed routing.

  • dfm: Design-for-manufacturing steps, primarily metal fill.

  • write: Writing out final views of the design (GDSII, etc.).

The synthesis, floorplan, place, cts, and route steps support parallel execution to explore different strategies. This can be configured by setting the corresponding *_np argument to a value greater than 1.

Args:
  • name (str, optional): The name of the flow. If not provided, it defaults to ‘asicflow-<language>’.

  • language (str): The hardware description language of the design. One of ‘verilog’, ‘systemverilog’, ‘systemverilog-sv2v’, ‘chisel’, ‘vhdl’, or ‘hls’.

  • syn_np (int): Number of parallel synthesis jobs to launch.

  • floorplan_np (int): Number of parallel floorplan jobs to launch.

  • place_np (int): Number of parallel placement jobs to launch.

  • cts_np (int): Number of parallel clock tree synthesis jobs to launch.

  • route_np (int): Number of parallel routing jobs to launch.

2.1.5. asicflow-hls / 4#

A configurable ASIC compilation flow.

This flow targets ASIC designs, taking RTL through a complete synthesis, place-and-route, and finishing flow.

The flow is divided into the following major steps:

  • elaborate: RTL elaboration using Slang.

  • synthesis: RTL synthesis using Yosys.

  • floorplan: Floorplanning, including macro placement, tapcell/endcap insertion, power grid generation, and pin placement.

  • place: Global and detailed placement.

  • cts: Clock tree synthesis and post-CTS timing repair.

  • route: Global and detailed routing.

  • dfm: Design-for-manufacturing steps, primarily metal fill.

  • write: Writing out final views of the design (GDSII, etc.).

The synthesis, floorplan, place, cts, and route steps support parallel execution to explore different strategies. This can be configured by setting the corresponding *_np argument to a value greater than 1.

Args:
  • name (str, optional): The name of the flow. If not provided, it defaults to ‘asicflow-<language>’.

  • language (str): The hardware description language of the design. One of ‘verilog’, ‘systemverilog’, ‘systemverilog-sv2v’, ‘chisel’, ‘vhdl’, or ‘hls’.

  • syn_np (int): Number of parallel synthesis jobs to launch.

  • floorplan_np (int): Number of parallel floorplan jobs to launch.

  • place_np (int): Number of parallel placement jobs to launch.

  • cts_np (int): Number of parallel clock tree synthesis jobs to launch.

  • route_np (int): Number of parallel routing jobs to launch.

2.1.6. asicflow-bluespec / 5#

A configurable ASIC compilation flow.

This flow targets ASIC designs, taking RTL through a complete synthesis, place-and-route, and finishing flow.

The flow is divided into the following major steps:

  • elaborate: RTL elaboration using Slang.

  • synthesis: RTL synthesis using Yosys.

  • floorplan: Floorplanning, including macro placement, tapcell/endcap insertion, power grid generation, and pin placement.

  • place: Global and detailed placement.

  • cts: Clock tree synthesis and post-CTS timing repair.

  • route: Global and detailed routing.

  • dfm: Design-for-manufacturing steps, primarily metal fill.

  • write: Writing out final views of the design (GDSII, etc.).

The synthesis, floorplan, place, cts, and route steps support parallel execution to explore different strategies. This can be configured by setting the corresponding *_np argument to a value greater than 1.

Args:
  • name (str, optional): The name of the flow. If not provided, it defaults to ‘asicflow-<language>’.

  • language (str): The hardware description language of the design. One of ‘verilog’, ‘systemverilog’, ‘systemverilog-sv2v’, ‘chisel’, ‘vhdl’, or ‘hls’.

  • syn_np (int): Number of parallel synthesis jobs to launch.

  • floorplan_np (int): Number of parallel floorplan jobs to launch.

  • place_np (int): Number of parallel placement jobs to launch.

  • cts_np (int): Number of parallel clock tree synthesis jobs to launch.

  • route_np (int): Number of parallel routing jobs to launch.

2.1.7. ASIC Subflows#

The ASIC flow is assembled from the following stage-specific subflows. They can be used on their own to run or debug an individual stage of the back-end.

2.1.7.1. cleanup_synthflow#

A flow that performs only the synthesis cleanup portion of the ASIC flow.

This flow is useful for quickly checking that a design can be successfully cleaned up after synthesis without running floorplanning or timing analysis. It includes the removal of synthesis buffers and dead logic.

2.3.5. synflow-hls / 4#

A configurable ASIC synthesis flow with static timing analysis.

This flow translates RTL designs into a gate-level netlist and then performs static timing analysis (STA) on the result. It allows for parallel execution of both synthesis and timing steps to explore different strategies or speed up execution.

The flow consists of the following steps:
  • elaborate: Elaborates the RTL design from its source files.

  • synthesis: Translates the elaborated RTL into a gate-level netlist

    using Yosys.

  • timing: Performs static timing analysis on the synthesized netlist

    using OpenSTA.

2.5. Design Verification Flows#

Flows for simulating and verifying a design. Each variant targets a specific simulator (and optionally cocotb-based testbenches).

2.5.1. dvflow-icarus / 0#

A configurable constrained random stimulus DV flow.

The verification pipeline includes the following steps:

  • compile: RTL sources are compiled into an intermediate format.

  • sim: The compiled design is simulated with a generated testbench.

The dvflow can be parametrized using the ‘np’ parameter. Setting ‘np’ > 1 results in multiple independent verification pipelines being launched in parallel.

Supported tools are:

  • ‘icarus’: Compiles and simulates with the Icarus Verilog simulator.

  • ‘icarus-cocotb’: Compiles with Icarus and runs cocotb Python testbenches.

  • ‘verilator’: Compiles and simulates with Verilator.

  • ‘verilator-cocotb’: Compiles with Verilator and runs cocotb Python testbenches.

  • ‘xyce’: Simulates a netlist with the Xyce circuit simulator.

  • ‘xdm-xyce’: Converts a design to a Xyce-compatible format and simulates.

2.8. Signoff Flows#

Flows that combine the physical verification steps into a single signoff flow.

2.8.1. signoffflow#

A flow for running LVS/DRC signoff on a GDS layout.

This flow performs two key physical verification steps in parallel:

  1. Design Rule Checking (DRC) using Magic.

  2. Layout Versus Schematic (LVS) checking using Netgen.

The LVS step first requires extracting a SPICE netlist from the layout, which is also handled by Magic. A final ‘join’ step ensures that both DRC and LVS tasks must complete successfully for the flow to finish.

2.10.7. generate_rcx / 0#

A flow to generate OpenRCX parasitic extraction decks for OpenROAD.

This flow automates the process of characterizing a parasitic extraction tool to generate the necessary configuration files (RCX decks) for OpenROAD’s built-in OpenRCX engine. It works by comparing the output of a third-party “golden” extraction tool against OpenRCX’s results and calibrating OpenRCX accordingly.

The flow consists of the following main steps for each specified corner:

  1. bench: A benchmark design with simple structures is created.

  2. pex: A user-provided third-party PEX tool is run on the benchmark

    to generate a “golden” SPEF file.

  3. extract: The golden SPEF is used to generate a calibrated OpenRCX

    deck.
