fixed-point in simvision

wangyunxin

Delta_ V1 delta_ V2 delta_ V3 are all 20 bit signals, but in my Verilog code, they are processed as signed fixed-point numbers, with 1 sign bit, 4 integer bits, and 15 decimal bits. So he is actually a real number between -10 and+10, but simvision's radius can only be set to binary decimal, as shown in the above figure. I can only see its decimal value now. How can I set the form of its fixed-point number to facilitate my debugging? My simvision version is also in the picture

  • Yes this can be done in SimVision by creating an "expression" from the original signal. You can either do it manually, or load the attached Tcl widget in order to get a helper GUI.
