Part of the EDAcation family
An interactive, browser-based visualiser for nextpnr place-and-route results. Inspect the placement and routing of your FPGA design directly in the browser - no installation required. Part of the EDAcation open-source FPGA toolchain education platform.
nextpnr mode
Run nextpnr with the --write and
optional --report flags to produce the
JSON files, then load them here.
nextpnr-ice40 --hx1k --package tq144 \ --json design.json \ --write place.json \ --report report.json nextpnr-ecp5 --25k --package CABGA256 \ --json design.json \ --write place.json \ --report report.json
EDAcation mode
Use the routed.nextpnr.json file
produced by the
EDAcation VS Code extension.
This single file already contains the chip family, device, placement data and
timing report.
