13.3 EDK-MPMC: ERROR:Pack:2501 - Symbol " "of type MCB has a property "MEM_DDR3_WRT_RECOVERY" with an illegal value of "2"
描述
I have an EDK based MPMC design targeting Spartan-6 FPGA. I am getting the following error during implementation:
What is the root cause for this? How do I fix this?
ERROR:Pack:2501 - Symbol "CPU_INST/sdram_0/sdram_0/mpmc_core_0/gen_spartan6_mcb.s6_phy_top_if/mpmc_mcb _raw_wrapper_0/samc_0" of type MCB has a property "MEM_DDR3_WRT_RECOVERY" with an illegal value of "2".
解决方案
The root cause behind this error is the clocking for MPMC. Please check the Recommended Value under section "Target Operating Frequency Ranges by FPGA Family" of the MPMC data sheet, and update the MPMC values accordingly.
