use inferrable power of 2 memory size on Intel boards #309

Closed tpwrules closed 1 year ago

tpwrules commented 1 year ago

For whatever reason, Quartus is unable to infer the integrated_sram memory when its size is not a power of two. This is confirmed using Quartus 20.1.1 and Quartus 18.1. As a result, these boards take excessively long to build and might not fit. The memory size has already been reduced on some of them in an attempt to fix this issue.

To fix this issue for all of them, the size on all Intel boards is reduced to the next lowest power of two. I've confirmed that all boards build, fit, and pass timing using Quartus 20.1.1. I've also confirmed that De10Nano can still boot the demo image.
