Re: magma problem

What happens when you "data list $m/pin:<pin name> , does it return 1? Also try to do "data find $m .*<pin_name>* -regexp -hier -type pin " ,
If data find cannot find it, then tool cant see the pin...may be you can export verilog netlist using export verilog and see if the pin is present and whats the pin name? [] brackets, hier sep , if you flatteneded the design etc all affect this..

also are you querying for "mpin" or "pin" . mpin is for model and pin is for cell ..repeat the above data command using -type mpin and check again..if nothing works you have an issue with your data itself...

Re: magma problem

You may want to use the command 'data invalidate power' before running power analysis for the second time. This will invalidate the power results from the previous analysis.
