Certain CPRI IP Core Variations Fail Simulation in the Cadence NCSIM Simulator - Certain CPRI IP Core Variations Fail Simulation in the Cadence NCSIM Simulator Description CPRI IP core variations with autorate negotiation turned on that target an Arria V GZ device or a Stratix V device, fail simulation in the Cadence NCSIM simulator. Resolution Use a different simulator to simulate these variations. This issue has no workaround for the NCSIM simulator. This issue will be fixed in a future version of the CPRI MegaCore function.
