Tcl‐Tk for EDA Tool

The Tool command language (Tcl)/Toolkit (Tk) scripting language has become the de‐facto standard for electronic design automation (EDA) tools and computer‐aided design (CAD) tool application. Vivado is an EDA tool developed by Xilinx that can be controlled using a Tcl script. There is an in‐built command in Tcl to read and write files to a local directory and create a directory dynamically, create a project, add files to the project, then synthesize, implement and generate a report. The Vivado tool writes a journal file with extension .jou into the directory from where the tool has been launched. Users can get help directly from the Tcl Console, and every command supports the –help command‐line argument. In Tcl mode, all the steps for implementing digital circuit with the Vivado EDA tool can be assembled once and all the steps will be executed in the background.
