10.1 UniSim/SimPrim-: # Warning : Address DADDR=1010110 is unsupported at DCM_ADV

Description

Keyword: UniSim, SimPrim, Address, DADDR, DCM_ADV 

 

When I try to set the phase shift value to "Direct" through DRP, I receive the following warning and PSDONE does not assert. Why?

Solution

This feature is not supported in the simulation model. That is, you cannot send address 56h to set CLKOUT_PHASE_SHIFT to DIRECT. 

 

Instead, you will have to set the CLKOUT_PHASE_SHIFT attribute to "direct" in the DCM instantiation, and then you can write the desired tab value 0-3FFh (DI) (0-1023 tabs) to DADDR 55h. 

 

There are currently no plans to support this feature in the simulation model.
