Title: annotating the DC operating point of subcircuits Post by Peter Kurahashi on Feb 10th, 2011, 4:12pm Hello, I am running Virtuoso version 6. I have a cell with multiple MOSFETs and I would like to annotate the operating point information of one of the MOSFETs on the cell symbol. I understand somewhat how CDF and Interpreted Labels are used when annotating the MOSFETs themselves. What I don't know is how to access their information from different levels of hierarchy. As an example: I say I have a cell called TOP_CELL. In this cell there is an array of MOSFETs called M0<1:5>. I would like to annotate at the TOP_CELL symbol, vdsat of M0<1>. Thanks! Peter |
Title: Re: annotating the DC operating point of subcircuits Post by Andrew Beckett on Feb 12th, 2011, 2:57pm Hi Peter, Currently you have to use the opParamExprList property in the simInfo for the simulator you want, to map the lower level data to the higher level. I suggest you search for opParamExprList in cdnshelp to find out how to do it. Hopefully we'll be doing something to avoid the need to modify the CDF to do this, but for now, this is really the only way. Best Regards, Andrew. |
