7318 - Radiant version 2023.2 SP1 and older: How do I change the TCK Low Width Delay to above 10x in Reveal Analyzer?

Description:

See the following steps to set the TCK Low Width Delay to >10x:

1. Program a device with the Reveal core

2. Create a .rva file

3. Edit the .rva file in a text editor. Change the following line:

4. Save the .rva file in your text editor and Radiant.

5. Verify if Reveal Analyzer is working

 

If you are unable to create a .rva file, please create one using the rva_new_project Tcl command. This will allow users to create a .rva file without needing to scan the device. 

 

See the following from Lattice Radiant Help:

 

Here are the detailed steps to use this Tcl command:

 1. Make sure that you already have a .rvl file

 2. Go to the Tcl Console

 3. Type the following command: rva_new_project -rva "<file_name.rva>" -cable USB2 -rvl "<file_name.rvl>" -dev "<device>-X" -port 0 -xcf ""

 > Note that you may need to change some parameters to suit your scenario like port, cable, etc.

 4. Add the .rva file to your Debug Files using either Tcl or GUI:

 

This is also planned to be updated in GUI in a future Radiant release.
