I did a quick search of "Vivado simulator" in the forum and this is the only thread that looked appropriate to point to my elink2 fpga simulator tutorial and script (
https://github.com/peteasa/parallella/w ... Simulation) that I have just created that uses my parallella development project. My parallella development project provides a good starting point for FPGA / software development for the parallella board. At present I am only using the elink2 fpga, but plan to move to use the oh fpga projects in the future.
The most important thing for any fpga sandbox would be to ensure that the i2c interface is operational as this is used in the boot loader to configure the regulators. An alternative of course would be to develop your own boot loader.. but then thats another thing to go wrong and so the FPGA sandbox should I think not require an updated boot loader.
I will be interested to see over time how easy it is to track different versions of Vivado simulator!
