1. Schema#
1.1. Keywords#
- default#
Reserved SiliconCompiler schema key that can be replaced by any legal string.
1.2. Parameter Fields#
- copy#
Whether to copy files into build directory, applies to files only
- enum#
List of strings containing the set of legal values for this parameter.
- example#
List of two strings, the first string containing an example for specifying the parameter using a command line switch, and a second string for setting the value using the core Python API. The examples can be pruned/filtered before the schema is dumped into a JSON file.
- hashalgo#
Hashing algorithm used to calculate filehash value.
- help#
Complete parameter help doc string. The help string serves as ground truth for describing the parameter functionality and should be used for long help descriptions in command line interface programs and for automated schema document generation. The long help can be pruned/filtered before the schema is dumped into a JSON file.
- lock#
Boolean value dictating whether the parameter can be modified by the set/get/add core API methods. A value of True specifiers that the parameter is locked and cannot be modified. Attempts to write to to a locked parameter shall result in an exception/error that blocks compilation progress.
- node#
Dictionary containing fields whose values may vary on a per-step/index basis. Sub-fields are described in Per-node Parameter Fields
- notes#
User entered ‘notes’/’disclaimers’ about value being set.
- pernode#
Enables/disables setting of value on a per node basis. Allowed values are ‘never’, ‘option’, or ‘required’.
- require#
Boolean value dictating whether the parameter is required for a run.
- scope#
Scope of parameter in schema
- switch#
String that specifies the equivalent switch to use in command line interfaces. The switch string must start with a ‘-’ and cannot contain spaces.
- shorthelp#
Short help string to be used in cases where brevity matters. Use cases include JSON dictionary dumps and command line interface help functions.
- type#
The parameter type. Supported types include Python compatible types (‘int’, ‘float’, ‘str’, ‘enum’, and ‘bool’) and two custom file types (‘file’ and ‘dir’). The ‘file’ and ‘dir’ type specify that the parameter is a ‘regular’ file or directory as described by Posix. All types can be specified as a Python compatible list type by enclosing the type value in brackets. (ie. [str] specifies that the parameter is a list of strings). Types can also be specified as tuples, using the Python-like parentheses syntax (eg. [(float,float)] specifies a list of 2-float tuples). Input arguments and return values of the set/get/add core methods are encoded as native Python types. When exporting the manifest to JSON, values are converted to the equivalent JSON type. Most types have a straightforward mapping, but note that values of “None” get mapped to “null”, and both tuples and lists get mapped to arrays. Tuple-type parameters have their values normalized back into tuple form when a JSON manifest is read in.
- unit#
Implied unit for parameter value.
1.3. Per-node Parameter Fields#
The following fields are specified inside the node dictionary on a per-step/index basis.
Default values for each field are stored under the special keys "default", "default", and global values are specified under the special keys "global", "global".
File author. The author string records the person/entity that authored/created each item in the list of files within ‘value’ parameter field. The ‘author’ field can be used to validate the provenance of the data used for compilation.
- date#
String containing the data stamp of each item in the list of files within ‘value’ parameter field. The ‘date’ field can be used to validate the provenance of the data used for compilation.
- filehash#
Calculated file hash value for each file in the ‘value’ field of the parameter.
- signature#
String recording a unique machine calculated string for each item in the list of files within ‘value’ parameter field. The ‘signature’ field can be used to validate the provenance of the data used for compilation.
- value#

For example a PDK with support for 9 and 12 track libraries might have ‘libarchs’ called 9t and 12t. The standard filetype for specifying place and route design rules for a process node is through a ‘lef’ format technology file. The ‘filetype’ used in the aprtech is used by the tool specific APR TCL scripts to set up the technology parameters. Some tools may require additional files beyond the tech.lef file.

A list of piped together grep commands. Each entry represents a set
of command line arguments for grep including the regex pattern to
match. Starting with the first list entry, each grep output is piped
into the following grep command in the list. Supported grep options
include -v and -e. Patterns starting with “-” should be
directly preceded by the -e option. The following example
illustrates the concept.
UNIX grep:
$ grep WARNING place.log | grep -v "bbox" > place.warnings
SiliconCompiler:
chip.set('task', 'openroad', 'regex', 'place', '0', 'warnings',
["WARNING", "-v bbox"])
The “errors” and “warnings” suffixes are special cases. When set,
the number of matches found for these regexes will be added to the
errors and warnings metrics for the task, respectively. This will
also cause the logfile to be added to the ['tool', <tool>, 'task', <task>, 'report', ...] parameter for those metrics, if not already present.

List of acceptable versions of the tool executable to be used. Each
entry in this list must be a version specifier as described by Python
PEP-440.
During task execution, the tool is called with the ‘vswitch’ to
check the runtime executable version. If the version of the system
executable is not allowed by any of the specifiers in ‘version’,
then the job is halted pre-execution. For backwards compatibility,
entries that do not conform to the standard will be interpreted as a
version with an ‘==’ specifier. This check can be disabled by
setting ['option', 'novercheck'] to True.

the version number. Common switches include -v, -version,
--version. Some tools may require extra flags to run in batch mode.
1.5. Nested Schemas#
The SC schema has two special top-level categories that store nested subsets of the schema rather than unique parameters.
1.5.1. history#
The “history” prefix stores configuration from past runs, indexed by jobname.
Values are stored automatically at the end of run(), and only parameters tagged with the ‘job’ scope are stored.
This can be used to go back and inspect the results of old runs.
As a shortcut for accessing these stored values, most of the schema access functions support an optional job keyword arg.
For example, the following line returns the number of errors from a synthesis step run as part of a job called “job0”:
chip.get('metric', 'error', job='job0', step='syn', index='0')
1.5.2. library#
The “library” prefix stores the schema parameters of library chip objects that have been imported into the current chip object, keyed by library name. These values are accessed directly using the schema access functions. For example, the following line returns the path to a LEF file associated with a library called “mylib”:
chip.find_files('library', 'mylib', 'output', stackup, 'lef')
1.5.3. Journaling#
The schema can support tracking of schema transactions which modify the data in the schema. The transactions are recorded in the schema in cfg[‘__journal__’], which is a list of the transactions since recording began. Each record for the journal contains:
- type#
Type of transactions performed, can be one of: set, add, remove, and unset
- key#
Keypath that was modified
- value#
New value for keypath, in record types which are destructive, this is None
- field#
Schema field that was modified, in record types which are destructive, this is None
- step#
Step that was modified, in record types which are destructive, this is None
- index#
Index that was modified, in record types which are destructive, this is None
To control the journaling:
chip.schema._start_journal() # To start recording transactions
chip.schema._stop_journal() # To stop recording transactions and remove all records of transactions
chip.schema._import_journal(other_schema) # To import and playback transactions, usually used to merge together a node manifest with the main manifest in SiliconCompiler
