1097 differences from 210 file revisions in 2 real world projects shows that the ordering of code actually matters in practice when it comes to computing differences.
verible-verilog-diff compares two SystemVerilog source files and reports the first lexical difference. Equivalence is determined by the comparison --mode.
Vera is a command-line tool that allows you to verify whether two different Verilog implementations produce the same outputs given the same inputs. This page will walk through basic usage patterns.
Our differencing algorithm takes two versions of a Verilog design file and first extracts abstract syntax trees (ASTs). Traversing the trees top-down, for each level, it uses the longest common sequence.
This paper presents Vdiff, an instantiation of this position-independent differencing algorithm for Verilog HDL. To help programmers reason about the differences at a high-level, Vdiff outputs syntactic.
