Documentation for MMMC flow with CPF

mamsadegh

Hi,

In SOC Encounter Users Guide, Chapter 43, "Performing Multi-Mode Multi-Corner Timing Analysis and Optimization" , describes MMMC flow completely however, I feel this description is supposing that you don't have a CPF file in your design, since most of the parts in the flow will be actually done in the CPF file and we don't need to do them manually. 

Is this correct?

In other words, The ".view" file, which is used for configuring MMMC, should be created automatically from CPF. Right now, as what I see from version 10.11 of encounter, this does not happen and you should create the .view manually. 

Is there any documentation , describing MMMC flow, considering also CPF file created and loaded for the design? or any script examples? 

thanks

    Ok, I read the solution.

    So, when I issue , "loadCPF" and "commitCPF" for my design in encounter, the analysis views will be created automatically based on the CPF file and all I need to do is just to add the proper RC corner to each analysis view. 

    more over, 

    when you load the design for the first time in encounter environment to perform initial place&route, the CPF will be read automatically by the scripts (produced by RC compiler) however, when you performed P&R and you stored the design, if your Restore it, CPF is not read and you should do this part yourself. 

    more over, this "viewDefinition" file , which is created automatically by the tool when storing the design, should be cleared or should 

    be commented completely , because this part is what you should do yourself through your script. 

    is that correct?

     

    regards
