Resource Estimation Backend

The resources estimation backend aims to provide a size estimation for the hardware that Calyx generates. Currently, it only supports estimation for std_reg, comb_mem_*, and seq_mem_* primitives, but more primitives will be added.

Running the resource estimation backend

  1. Run cargo build if you haven't built the compiler already.
  2. Run fud e path/to/futil.file --to resources. This should tally up the primitives used in the program and output a CSV with the number of instantiated primitives according to their attributes.

To output the CSV to a file, you can use -o myfile.csv. If you would like to see an English summary of the CSV as well as the estimated size of the hardware (counting only the supported primitives), add the verbose flag -vv to your fud command.
