Modeling and verification of a programmable mixed-signal device using Verilog

The use of behavioral modeling in Verilog-AMS is applied to the design of a programmable mixed signal device. In order to illustrate the possible increases in simulation efficiency, various simulation and modeling techniques arc compared for a mixed-signal application. A speedup of two orders of magnitude can be achieved in full system simulation with low loss of accuracy. A full system model using these techniques facilitates system development, testing, and application development.
