Globals

The global file contains global signal names for power (Vdd), ground (GND), and the chip reset signal (Reset). It also uses the sigtype attribute so that tools can associate these signals with the appropriate type.

pint SIG_POWER = 0,
     SIG_GROUND = 1,
     SIG_RESET = 2;
 
bool Vdd, GND, Reset;
 
Vdd @ [sigtype = SIG_POWER];
GND @ [sigtype = SIG_GROUND];
Reset @ [sigtype = SIG_RESET];
