* | Remove isValidBelForCell | gatecat | 2021-02-16 | 1 | -8/+17 |
| | | | | | | | | | | | | | | | | | This Arch API dates from when we were first working out how to implement placement validity checking, and in practice is little used by the core parts of placer1/HeAP and the Arch implementation involves a lot of duplication with isBelLocationValid. In the short term; placement validity checking is better served by the combination of checkBelAvail and isValidBelForCellType before placement; followed by isBelLocationValid after placement (potentially after moving/swapping multiple cells). Longer term, removing this API makes things a bit cleaner for a new validity checking API. Signed-off-by: gatecat <gatecat@ds0.me> | ||||
* | refactor: Replace getXName().c_str(ctx) with ctx->nameOfX | D. Shah | 2021-02-02 | 1 | -3/+3 |

* | ecp5: Proof-of-concept using IdStringList for bel names | D. Shah | 2021-02-02 | 1 | -4/+4 |
| | | | | | | | | | | | This uses the new IdStringList API to store bel names for the ECP5. Note that other arches and the GUI do not yet build with this proof-of-concept patch. getBelByName still uses the old implementation and could be more efficiently implemented with further development.
