// STAMPING EXAMPLES
//OLD WAY
//CONNECT metal2 welltie BY contact
//CONNECT well welltie
//After the Connect operations, all polygons
//belong to net VDD.

 

//STAMP EXAMPLE #1
CONNECT metal2 welltie BY contact
s_well = STAMP well BY welltie
//Doing these steps indpendent of the STAMP operation generates a *warning* due
//to conflicting net IDs and outputs nothing to derived layer S_WELL.

 

//STAMP EXAMPLE #2
CONNECT metal1 metal2 BY via
stamped_contact = STAMP contact BY metal1
stamped_well = STAMP well BY stamped_contact
bad_well {
@ bad_well: Find wells that have a stamp violation
well NOT stamped_well
}

 

//STAMP EXAMPLE #3
CONNECT metal1 metal2 BY via
stamped_contact = STAMP contact BY metal1
stamped_well = STAMP well BY stamped_contact
bad_well_contacts {
@ bad_well: Find contacts that form a soft connection
badwell = well NOT stamped_well
contact INTERACT badwell }
