8. Remote processing

The SiliconCompiler project supports a remote processing model that leverages the cloud to provide access to:

Pre-configured tool installations.

Warehouse scale elastic compute.

NDA encumbered IPs, PDKs, and EDA tools.

For command line compilation, remote processing is turned on with the ‘-remote’ option. Results from a remote compilation should be identical to results from a local compilation.

echo "module flipflop (input clk, d, output reg out); \
always @ (posedge clk) out <= d; endmodule"> flipflop.v
sc flipflop.v -remote

Remote processing is also supported from the Python interface when the ‘remote’ parameter is set to ‘True’.

chip.set('remote', True)

For security reasons, only a subset of the full Schema parameters is currently supported. Values for disallowed keypaths will be silently dropped by the server. In addition, note that the load_target() function will be re-run on the server, to ensure targets are set up with their default configurations. The following table documents the list of supported remote parameters and any associated restrictions.
