cwviz is a tool for visualizing specially-annotated Verilog files. It allows you to precisely control and visualize the layout of a circuit without having to use actual circuit layout tools. It also allows annotating the visualizations based on timing information from a few different sources.

Usage

cwviz [OPTION] ... verilog_file

-h, --help:
  Show this help
-o f, --out f
  Output to file f instead of to stdout
-c f, --config f
  Use f as the YAML configuration file
-s f, --scot-file f
  Use f as the SCOT timing file. Currently only supports
  visualizing a *single* .out file
-b, --absolute-delay
  Use absolute scot delays (per-cell)
-m name, --module-name name
  Visualize module "name". Defaults to the first module in the file,
  whatever that might be
-a, --autosize
  Automatically determine sizes by reading comments in the verilog
  argument
-l, --check-overlap
  Check for overlap in cells
-v, --verbose
  Be verbose
