|/ | | | | | | | | | | 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>
