Starting points for design understanding and debugging of a Hardware Description Language (HDL) design are generated waveforms. However, waveform viewing is still a highly manual and tedious process, and unfortunately, there has been no progress for automating the analysis of waveforms. Therefore, we introduce the Waveform Analysis Language (WAL) in this paper. WAL allows to create and execute analysis programs on waveforms. We have realized WAL as a Domain Specific Language (DSL). This design choice has many advantages ranging from a natural expressiveness of a waveform analysis problem to providing an Intermediate Representation (IR) well-suited as a compilation target from other languages.We demonstrate the capabilities of WAL in four case studies, covering the analysis of hardware performance of different RISC-V processors, combined hardware/software profiling, the usage of WAL to analyze bus transactions, and the implementation of a new embedded DSL using WALs macro system.
