Himbaechel GUI #1295

Open mmicko opened 7 months ago

mmicko commented 7 months ago

This extends Himbaechel API with additional methods for drawing bels, wires and pips. There is also configuration attribute to control if some of these are used and also do change in coordinate system (y axis).

Was mostly mimic what we do on ECP5 and XO2/3, and was not sure about equivalent for tile_wire (mapped to GfxTileWireId) so used flags for now, since it anyway keeps some additional custom info.

First few commits are mostly cleanup and fixes of some old standing GUI issues.

Would add at least basic things in Xilinx and Gowin when we agree on API level. Please do comment and suggest changes.

@gatecat Documentation is not added yet, but main question I have is if using tilewire as additional data is fine (need to bump db version in that case as well) ? not sure if there is other way we can actually use to determine which wire to draw.
