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.
