this is the command I ran:
`~/vtr-verilog-to-routing/vpr/vpr k4_N4_tileable_40nm.xml xor_cipher.blif --clock_modeling route`
vpr_arch is from https://github.com/lnis-uofu/OpenFPGA/blob/master/open…

As the arachne-pnr github says: Arachne-pnr is not maintained anymore; use nextpnr instead, which is a complete functional replacement with major improvements.
The commands to use nextpnr-ice40 wit…

While working on the Analytical Placer, I generated a very basic clustering and cluster placement. The quality of both of these was meant to be low as this is mainly just a PoC flow through VPR. These…

Hi there,
I am quite unsure if this issue stems from PyRTL itself and am looking for some feedback/suggestions.
I have a flow where I am doing timing analysis on VHDL code.
`VHDL -> GHDL plug…

Verilog to Routing supports using Quartus as a frontend for synthesis and then VtR for doing the place and route. You can find out more about this flow @ http://www.eecg.utoronto.ca/~kmurray/titan/fpl…

We have tried to execute the following RTL for subtracting two 4-bit numbers using the architecture file which supports carry chain adder. But the blif generated by the tools is giving the errors.

VPR can write post synthesis netlist (it is more of a post-pnr netlist IMO) as BLIF and Verilog. In the BLIF file unconnected input and output ports are tied to special nets named `__vpr__unconnXX` wh…
