* 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>
