Verilog to Routing -- Open Source CAD Flow for FPGA Research
VTR is currently supporting hard and soft logic mixing for multipliers. Having this feature for adders is also good since adders are used widely in a variety of designs.
#### Expected Behaviour We should have no compiler warnings #### Current Behaviour Fasm has a few warnings /home/runner/work/vtr-verilog-to-routing/vtr-verilog-to-routing/utils/fasm/test/test_lut.cpp:15:28: warning: comparison of integer expressions of different signedness: ‘size_t’ {aka ‘long unsigned...
#### Expected Behaviour We should have no compiler warnings. #### Current Behaviour Some warnings in vqm2blif: [ 50%] [BISON][VqmParser] Building parser with bison 3.8.2 /home/runner/work/vtr-verilog-to-routing/vtr-verilog-to-routing/libs/libvqm/vqm_parser.y:45.1-14: warning: deprecated directive: ‘%error-verbose’, use...
#### Expected Behaviour QoR checks should always pass on any PR to merge and the master branch. #### Current Behaviour However, due to an emergency on migrating to Ubuntu 22.04...
We have some unit tests (not just script-based regressions) but haven't made a guide of how to make more. We should add such a guide in the testing part of...
#### Expected Behaviour After migrating to Ubuntu 22.04, we see build compatibility loss due to the gcc and clang upgrades. For example, the supported gcc and clang versions are very...
There is a function named "sync_netlists_to_routing." This function synchronizes the results of packing and routing. During the routing, the pin that a net is connected to may change, and this...
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...
Hi, I am curious on what is the command for forcing the design to have the shortest routing, also the longest routing? Thanks! I do see there are --place_algorithm {bounding_box...
Currently, flat-router doesn't support graphics. When both "flat_routing" and "disp" options are set, VPR crashes. Until the graphic support is added, VPR should probably print an error message instead of...
