* Replace DelayInfo with DelayPair/DelayQuadgatecat2021-02-191-9/+9
| | | | | | | | | | | | | | | | | This replaces the arch-specific DelayInfo structure with new DelayPair (min/max only) and DelayQuad (min/max for both rise and fall) structures that form part of common code. This further reduces the amount of arch-specific code; and also provides useful data structures for timing analysis which will need to delay with pairs/quads of delays as it is improved. While there may be a small performance cost to arches that didn't separate the rise/fall cases (arches that aren't currently separating the min/max cases just need to be fixed...) in DelayInfo, my expectation is that inlining will mean this doesn't make much difference.

* 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>

* 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.
