relong Tests
These tests are borrowed from Reid Long's HDL Examples
repository. That repository was
intended to provide examples for how the conversions in this project could be
done. sv2v does not necessarily convert code as demonstrated in the examples.
Notably, sv2v does not create generate blocks when converted vectors with
multiple packed dimensions, uses localparams rather than macros for enum
conversion, and converts struct literals to concatenations, rather than
multiple statements.
Each test case (say, "foo") is comprised of the following files:
foo.sv: original SystemVerilogfoo.v: hand-converted Verilogfoo_tb.v: basic testbench exercising the given modules
The SystemVerilog source file is converted to Verilog using sv2v, and then both the converted file and the reference Verilog are simulated using Icarus Verilog. This produces VCD files for each which are expected to match exactly, except for the timestamp.
Modifications
The following differences exist between the tests in this folder and their corresponding versions in the source repository.
- The
inline_concatfiles were modified to remove a stray trailing semicolon. Though some tools allow for stray semicolons,iverilogdoes not. array.vpreviously had a custom implementation of$clog2, which was removed.cache_request.svwas modified to include a plain decimal literal to ensure coverage beyond the unbased-unsized literals.- The
cache_request2test is omitted. It was only an example for debugging a VCS-specific issue encountered withcache_request.
