| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some models have I/O cells that are IOBUFs, and other types (IBUFs and OBUFs) are obtained by feeding 1 or 0 to the OEN input. This is done with general-purpose routing so it's best to do it here to avoid conflicts. For this purpose, in the new bases, these special cells are of type IOBS (IOB Simplified). The proposed changes are compatible with bases of previous versions of Apycula and do not require changing .CST constraint files. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

|\ \ | | | | | | archapi: Use arbitrary rather than actual placement in predictDelay [breaking change]
| * | archapi: Use arbitrary rather than actual placement in predictDelaygatecat2021-12-1926-70/+89
|/ / | | | | | | | | | | | | | | | | | | | | | | This makes predictDelay be based on an arbitrary belpin pair rather than a arc of a net based on cell placement. This way 'what-if' decisions can be evaluated without actually changing placement; potentially useful for parallel placement. A new helper predictArcDelay behaves like the old predictDelay to minimise the impact on existing passes; only arches need be updated. Signed-off-by: gatecat <gatecat@ds0.me>
