| | | | | | | | | | | | | | | | This uses a new data structure for net.users that allows gaps, so removing a port from a net is no longer an O(n) operation on the number of users the net has. Signed-off-by: gatecat <gatecat@ds0.me>

| * gowin: recognize partnumbers of GW1NZ-1YRabbit2022-02-241-1/+1
|/ | | | | | | | | | | The model should be recognized by the partnumber, --family is needed only if the same partnumbers belong to different models. This is done in order to automatically generate parameters for calling nextpnr from Gowin files without problems: there also only partnumber is used and only in some cases the model is specified with the -name parameter and GW1NZ-1 is not such a case.

|/ | | | | | | | | The new primitive appears as an amalgamation of two existing OBUF primitives. Compatible with older versions of apicula, although, of course, using TLVDS_OBUF with old databases will not bring the desired result, but no crash. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

|/ | | | | | | | | | | The current version of Crosslink-NX Family Data Sheet lists the high frequency oscillator maximum frequency as 481.5MHz (that is, 7% higher than its nominal 450MHz): https://www.latticesemi.com/-/media/LatticeSemi/Documents/DataSheets/CrossLink/FPGA-DS-02049-1-2-1-CrossLink-NX-Family.ashx?document_id=52780 Older documents listed a wider frequency range but ±7% is the range for production parts.

|/ / | | | | | | | | | | | | | | | | | | | | In the vendor IDE, there's a device family named GW1N-9C (which seems to mean C revision of GW1N-9), in which the model numbers are all the same with GW1N-9. Add an option to nextpnr-gowin to allow manually specified family for this situation. Signed-off-by: Icenowy Zheng <icenowy@aosc.io>
