Verilog to Routing -- Open Source CAD Flow for FPGA Research
#### Description Adds a `-temp_dir ` argument to both the `run_vtr_task.py` and `parse_vtr_task.py` scripts, allowing the user to specify an output directory separate from the standard task directory structure in...
1. Add the regression test for the cluster tight floorplan, as mentioned in #2089. 2. Solve the bug that vpr failed to find the sdc_file and read_vpr_constraints file when specifying...
In router_lookahead_map ([this line](https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/a7cd8f99740d64acb92c470fd5b9069c1f0e04c5/vpr/src/route/router_lookahead_map.cpp#L329)), the expected delay is multiplied by (1-criticality). It seems backward to me. I think the delay should be multiplied by the criticality factor, and congestion should...
How can I use the routing resource map for placement and routing? Even though I read in the wiring resource diagram, VPR still requires me to provide the xml description...
#### Description Bring the tileable routing resource graph builder from OpenFPGA to VPR. Full details about the tileable routing resource graph builder can be found at X. Tang, E. Giacomin,...
#### Description In this PR, the Yosys script for the Yosys+Odin-II is updated to perform the synthesis for basic operations by Yosys. Then Yosys generates the BLIF file with unmapped...
In order to custom In order to customize the clustering strategy and speed up the program, some modifications are expected to be applied in the pack procedure. In the "cluster.cpp"...
As the dev version has updated the re_cluster function (re_cluster.h, re_cluster.cpp, re_cluster_util.h, re_cluster_util.cpp,), is there any example about the basic usage of re_cluster methods? Thank you very much.
There seems to be an issue with running the basic usage example for `run_vtr_flow` with `-start yosys`. #### Expected Behaviour In the [docs](https://docs.verilogtorouting.org/en/latest/yosys/quickstart/), the example invocation for running VTR with...
#### Description This unit test tests the functionality of librrgraph through I/O tests, specifically `rr_graph_reader` & `rr_graph_writer` #### Related Issue Other PRs that may impact RRGraph, #2066, #1999 Require to...
