You could write a post-place netlist as BLIF file with arachne-pnr --post-place-blif netlist.blif
and then convert it to JSON using Yosys with yosys -q -o netlist.json netlist.blif
.
@cliffordwolf yes, you are right. That works.
I am working on rendering engine that would produce SVG image of the FPGA array with logic functions and connections between them. I know that yosys is capable of producing result in JSON format, that is greatly simplifies further processing. Would it be possible to emit PNR information in JSON format from arachne-pnr?
