prga.passes.vpr.arch module¶

class prga.passes.vpr.arch.VPRArchGeneration(output_file, *, fasm=None)¶

Bases: prga.passes.vpr.arch._VPRArchGeneration

Generate VPR’s architecture description XML.

Keyword Arguments:
Parameters:	output_file (`str` of file-like object) – The output file. If the file name ends with “.gz”, the output file will be compressed using gzip
	fasm (`FASMDelegate`) – Overwrite the deafult fasm delegate provided by the context

_device(context)¶

_layout(context)¶

_layout_array(array, globals_, hierarchy=None)¶

_update_output_file(summary, output_file)¶

_update_summary¶

ios¶

key¶: Key of this pass.

class prga.passes.vpr.arch.VPRScalableArchGeneration(output_file, delegate, *, update_summary=False, timing=None)¶

Bases: prga.passes.vpr.arch._VPRArchGeneration

Generate a scalable version of VPR’s architecture description XML.

Keyword Arguments:
Parameters:	output_file (`str` of file-like object) – The output file. If the file name ends with “.gz”, the output file will be compressed using gzip delegate (`VPRScalableDelegate`) –
	fasm (`FASMDelegate`) – Overwrite the deafult fasm delegate provided by the context

WARNING: The routing graph generated by VPR during FPGA sizing and routing channel fitting is almost always different than the one generated by PRGA. Use the scalable architecture description only for exploring, and then use fixed layout and channel width for your real chip.
