* Start making use of getBelPinsForCellPin APIgatecat2021-02-101-1/+1
| | | | | | | | | | | | This replaces getNetinfoSinkWire with 3 new functions for different use cases. At the moment all existing code has been moved to getNetinfoSinkWire with phys_idx=0 so the build doesn't break; but this won't yet function properly with more than one sink. But it provides a base on which to work on refactoring the routers to support this case. Signed-off-by: gatecat <gatecat@ds0.me>
* refactor: Replace getXName().c_str(ctx) with ctx->nameOfXD. Shah2021-02-021-2/+1

* cleanup: Remove dead/unused codeD. Shah2021-01-281-28/+2
| | | | | | | Note that some '#if 0' code that might still be useful for debugging in the future has been retained. Signed-off-by: D. Shah <dave@ds0.me>

* Only print filenames for now, default onRoss Schlaikjer2020-08-301-54/+7
|
* Add option to print critical path source codeRoss Schlaikjer2020-08-301-0/+78
| | | | | | | In order to make debugging the critical path easier, add an option that will log the location each net was defined, if known. If the file that contains the definition is known, and is readable, also print the part of the source HDL responsible for the signal definition.
