MPMC2 - PlatGen issues the warning: "Unknown XCL bus <bus name> on IP <mpmc2 core>. Unable to verify line length"


The following warning from PlatGen occurs when generating netlists for an MPMC2 system containing MicroBlaze and the XCL PIMs:

"WARNING ** MicroBlaze - <microblaze instance name>

WARNING ** Unknown XCL bus "<xcl bus>" on IP

WARNING ** "<mpmc2 instance>". Unable to verify line

WARNING ** length."


You can safely discard this warning message. However, note that the XCL PIM only supports cache line lengths of four. Ensure that the parameters C_ICACHE_LINE_LEN C_ICACHE_LINE_LEN are both set to four (this is the default setting).
