Why can't I launch Qsys or the IP Parameter Editor? - Why can't I launch Qsys or the IP Parameter Editor? Description In the Quartus® II software version 14.0 and later, you may see that Qsys or the IP Parameter Editor fails to launch due to a lack of memory. The Java Virtual Machine needs a contiguous block of memory in order to startup. Resolution To work around this, go to Assignments > Settings > IP Settings > Maximum Qsys memory usage and change it to a lower value.
