This chapter introduces system functions for querying on elaboration status and simulation environments as well as system functions providing runtime support to the numerical solver and control of the simulation.
Elaboration Queries
Module ports need not be connected and module parameters may not be overridden when the module is instantiated. In some cases, the module evaluation could depend on the information of actual port connectivities and the status of the parameter override. Verilog-A provides system functions that can be used to query that information. ...
