There is one major problem with this node depth generator: It cannot execute the larger odgi files (LPA.og and DRB1-3123.og). I am currently using verilator to execute the Calyx code due to a bug in the interpreter, and verilator produces a stack overflow error (!). Verilator does not produce a stack overflow error on the implementation which does not use invoke statements.
What this version of the generator does bring to the table is multiplexing (yay!) I haven't done any tests to see how efficient it is (how close it gets to W/N), but the capability is there (for the smaller odgi files, anyways). I also added another group of node depth tests for multiplexing under test/depth/multiplexing.
There are also two files where I attempt to use the ref keyword; this implementation passes the basic tests on verilator (except LPA.og and DRB1-3123.og), but because of a bug with the ref keyword, multiplexing does not work. I left them in the repo because I hope that once the bug is fixed, multiplexing will be possible (and much easier) with the ref keyword, although perhaps they shouldn't be merged to the main branch yet?
