* gowin: add an option to manually specify familyIcenowy Zheng2022-02-061-6/+11
| | | | | | | | | | | 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>
* gowin: Add GUI.YRabbit2022-01-291-0/+1
| | | | | | | | | | | | | | | * Items such as LUT, DFF, MUX, ALU, IOB are displayed; * Local wires, 1-2-4-8 wires are displayed; * The clock spines, taps and branches are displayed with some caveats. 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>

* gowin: Use speed from chip base.YRabbit2021-11-051-4/+1
| | | | | | | Another simplification of the input regular expression, now the speed is taken from the base. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>
* gowin: Add partnumbers and packages to the chipdbYRabbit2021-11-041-1/+1
| | | | | | | | | | Instead of parsing the partnumber with a regular expression, a simple table is used. This is done because the structure of the partnumber changes as new features appear (e.g., ES instead of C6/I5) This commit does not yet disable the very first regular expression check.
