DE0-Nano TCL commands for quartus.stp control

I came across a post that talks about this communication. But again, no one from the community replied or clarified in 5 days. He/she learned by himself. Still there is a lot of room for VJTAG IP core. Intel should come with the detailed explaination with good examples. I am waiting let see when a response is posted by community, if at all. Here is the blog: https://community.intel.com/t5/Programmable-Devices/a-few-questions-about-using-Virtual-JTAG-ip-core/m-p/1266882#M79342
