Platform designer very slow when opening top level system (21.1 Std)

It seems like you are facing performance issues with Quartus Prime Standard 21.1 when working with your FPGA project, specifically related to opening the top-level QSYS file and during the Analysis & Synthesis.

An additional workaround to improve the performance within Platform Designer is to convert instantiated IPs within the System into 'Blackbox' mode. By doing this, the IP's validation routines are disconnected from the System, reducing the computational load on the tool. When changes to an IP's parameters are needed, the mode can be switched back to 'IP' mode, allowing you to modify the parameters for a specific .ip file. To achieve this, select an instantiated IP in the System and navigate to the 'Component Instantiation' tab, then choose 'Blackbox'. This action effectively disconnects the IP from the System temporarily, alleviating the processing load. This approach can be applied to all relevant IPs, and the IP can be reintegrated into the System only when parameter changes are required.

Your project seems to be quite resource-intensive, consuming around 80% of the ALM and 35% of the memory bits in an Arria 10 GX device. Such high resource utilization can lead to longer analysis and synthesis times. Consider optimizing your design to reduce the resource usage, or even considering a larger FPGA if it's within the project scope.

Review your project settings in Quartus. Make sure that the optimization settings are appropriate for your design. Some aggressive optimization settings might lead to longer compilation times. Adjusting to other settings might help.
