Title: Voltage dependent parameters in Spectre simulation Post by Minkyu Kim on Sep 28th, 2018, 7:38am Hi, I am trying to make some model which uses voltage-dependent parameters with user-defined function in Spectre language. But I cannot find any clues to do such thing in spectre, is it even possible? I know that there is VCVS or VCCS in Spectre, but what I am trying to do is use the output of the user-defined function in PWL resistors or capacitors. This means that the output type of the function should be parameter. In addition, I want to have array parameter which could simplify my code for several parameters to be used in the function. Is it possible? |

Title: Re: Voltage dependent parameters in Spectre simulation Post by Ken Kundert on Oct 2nd, 2018, 9:21pm Spectre. Verilog-AMS is a built-in feature of Spectre, and most other simulators designed for analog and mixed-signal ICs. There are a lot of example Verilog-A models on Verilog-AMS. You can find a how-to on modeling a simple nonlinear component in Varactors. -Ken |
