Accessing the RAM of a QEMU Emulated System from another Process

Sometimes it may be of interest to expose the RAM of a hardware platform emulated in QEMU to an outside process, e.g., for monitoring, testing, or co-simulation. The QEMU monitor allows to inspect the memory but is not necessarily the most practical tool when you need to access it from another process, e.g., a C program or an external simulator, maybe Questasim simulating a device written in SystemVerilog. In this post I will show how to make the memory of…

Running Questasim on any OS through Docker

Questasim When doing HDL simulation Questasim is one of our main tools. However it only runs on Windows and GNU/Linux. Although we¬† mostly use GNU/Linux machines Questasim is not compatible with all distributions. This mainly because of library version compatibility, albeit this being fixable, it is a pain to do (find out which library is the culprit and which version is needed). So creating a Docker image seems like a good solution. It provides a known fixed environment to Questasim…
