Saving nodes in spectre include file

akrebs

I am trying to adjust my list of saved nodes in a simulation depending on an ADE design variable.  i.e. if a certain part of a circuit is enabled for a simulation, the nodes in that part will get saved.

I have been trying to do this using a spectre include file within ADE-XL to define nodes to save.

 //start

save I131.*                //save all nodes inside instance I131

// This section is where I was trying to save depending on a design variable

// Couldn't get it to work

// diff_ac is a design variable in ADE

if ( diff_ac < 0.5 ) {

save I129.*

} else {

save I128.*

} 

//end 

 

The first save statement works, so the script is definitely getting read in. But, neither of the save statements in the if() statement working.  No errors, but no save either.  My understanding is that ADE design variables become parameters in spectre.  Is my if() statement used correctly?  Do I need to reference the design variables in a different way?

  • Brilliant Andrew. I have just used this trick to save all nodes or not; if(saveAllNodes>0.5 "path/saveAllNodes.scs" nil). As designers sometimes forget they have left all the nodes saved in the test editor then run corners in ADEXL and fill up the disk space then this global variable when set to 1 will be a good visual reminder before hitting run that you may be saving more data than you intend. Perhaps i need to open a new topic but for me a better idea is to have a warning come up before running corners if all the nodes are saved. Could there be a clever way at doing this?
