Use pattern matching in saving current (spectre)

The save statement takes a list of signals followed by some optional parameters as an argument.

save X[:param] ... [depth=num] [sigtype=node|dev|subckt|all]

• The parameters control pattern matching; 
• depth controls the depth of the pattern matching ( default: all hierarchical levels);
• sigtype defines the type of X (default value: node)

The following save statement can be used in post-layout simulation, when you want to check all the currents of a specific device that has a m other than 1:

save I0.MTP3319.*:d sigtype=subckt
