Corrects the situation when it is impossible to use IOBUF with two IOLOGIC elements at the same time - input and output. Addresses https://github.com/YosysHQ/nextpnr/issues/1275 This is done by dividing one IOLOGIC Bel into two - input IOLOGIC and output IOLOGIC plus checking for compatibility of the cells located there. At the moment, this check is simple and allows only the combination of DDR and DDRC primitives. Signed-off-by: YRabbit <rabbit@yrabbit.cyou> |
