Here’s the next in my ongoing list of tcl tips and tricks. Use foreach to break apart a list in to its components. In this example I’m working with a description of a temperature range. I’m told the description is a list that starts with the initial temperature, the middle value is the final temperature, and [...]
Tcl Tip of the Day
In EDA tcl is the scripting language. Tcl has its quirks but it’s extremely flexible and powerful… and often misunderstood. I’m going to try to start to semi-regularly post Tcl tips and tricks that might be helpful to EDA engineers and non-EDA engineers alike. So here goes…. Tip #1 Use {} braces to isolate a variable in [...]
