What is the size of the XPLA2 download file and how much device memory space do I need to store this?

Solution

The size of the download file varies with the design because a compression algorithm is employed. However, the maximum size of a configuration file (meaning no compression) for a XCR320 is 189,280 bits, and the maximum size of a configuration file for a XCR960 is 565,600 bits. Therefore, the designer should choose the size of the configuration PROM appropriately.
