Failed To Find Pll Reference Clock

Define core clock in the sdc fileSince the core logic is driven by another PLL, hence we need to manually define the core clock in the sdc file Open the HMC_mem_if_ddr3_emif_0_p0.sdc Figure below shows the block diagram of this reference design.

Thank you.

This allows two ports to be used to service a single bandwidth stream and also provide flexiblity to expand the interface data width.

Click Generate to generate the design Design Analysis 1. Bonding Interface Requirement You can only bond two HMCs with same memory configuration (same frequency, same timing parameters etc). The cause of the problem is RAPID_RECOMPILE_MODE set to ON which causes the afi_half_clk_reg to not be preserved in subsequent compiles. Set parameters for Memory Controller with UniHY'• PHY Settings Tab Select JEDEC DDR3 -1066E 1GB X8 Set Speed grade to 6.

But based on our previous related experimental > work, one-stage of our T-connector will be just fine. If that doesn't work, I know that I have had issues in placing PLL's in the past. Connect the blocks as shown in the diagram below: 2. To ensure minimum jitter on memory interface clock outputs, the PLL clock source should be a dedicated PLL input clock pin or an output of the neighboring PLL, and not go
