* Switch to potentially-sparse net users arraygatecat2022-02-2734-465/+442
| | | | | | | | 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>

For now, you can not create a project in the GUI because of possible conflict with another PR (about GW1NR-9C support), but you can specify the board in the command line and load .JSON and .CST in the GUI. Although ALUs are displayed, but the CIN and COUT wires are not. This is still an unsolved problem. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>
