llhd-sim

This is the reference simulator for LLHD, striving to be complete but as minimal as possible. Its goal is to serve as a starting point for developing more sophisticated simulators for hardware written in LLHD. As a secondary goal it acts as an application example of LLHD.

Roadmap and Milestones

• execute processes
• execute entities
• execute functions
• unary, binary instructions
• probe, drive instructions
• call instruction
• sig, inst instructions
• compare instruction
• return, branch instructions
• preserve hierarchy in VCD
• Milestone: basic simulator
• run simulation for limited time
• set breakpoints in processes/functions
• set breakpoints in entities
• step over, step into
• list source code extract, print values/signals
• interactive prompt
• Milestone: interactive debugger
