Verilog-AMS Eases Mixed Mode Signal Simulation

摘要

The ability to design and verify mixed mode (digital, analog, electrical, and non-electrical) systems is key to the development of new products for the ever expanding electromechanical market Although there are several individual point tools that can address specific phases of the development flow, tools to make the total process more seamless and less disparate should start to appear at the start of this new millennium, fueled by the introduction of Verilog-AMS Hardware Description Languages(HDL) and other analog HDL languages. The Language Reference Manual (LRM) for Verilog-AMS, developed by and available from the Open Verilog International (OVI) group, forms the basis for the new Verilog-AMS language. The document describes the extensions to the IEEE standard digital simulation language Verilog that enable the description of analog and nonelectrical behavior. The document soon to be made available to an IEEE standards organization has been going through the OVI standardization process since about 1995. Verilog-A simulators based on the OVI LRM 1.0 are currently available.
