Just like modifying the sources, customizing various parameters of Vivado CLI tools ( xvlog, xvhdl, xelab and xsim), adding plusargs, defines, etc.

Quick parameter / configuration adjustment.

2: Changing the source list is quick with any text editor Unlike the disaster that’s demonstrated in Figure 1, once you have your simulation flow and sources down in a bash script or a makefile, you can quickly modify said list with any text editor without having to use any sluggish GUI’s.įig.

Quick and easy addition/removal of sources.

In stark contrast, compiling, elaborating and simulating from the command line has some serious advantages: If you’ve used the Vivado GUI (and, I mean, surely you must have if you’re reading this) then you know how clunky the graphical interface is. 1: That's a lot of pixels just to add a source file Why bother? ⌗

In Part II, an example VHDL module is also included.įig. Note: This guide uses SystemVerilog as the language of choice, but everything discussed here is applicable to VHDL and Verilog too. In Part I, we will get familiar with using the Vivado CLI tools. In the following series of guides, I will give you all the information you need to quickly move your simulation out of the graphical Vivado project into a scripted flow for easy compilation, elaboration, and simulation, all done using the Command Line Interface (CLI). You probably feel that the interface is slow, and the number of windows and menus that must be navigated even for the most basic tasks is ridiculous. If you’re reading this post, you are likely frustrated with with the Xilinx Vivado GUI.

Part IV - IP core and Block Design integration into scripted flow (coming soon).Part III - Vivado Simulator flow using Makefiles.

Part II - Introduction to Bash scripting with Vivado tools.
