Lets Start Working with FPGA [Part 3]: How JTAG state machine works?

Hello fellows! so far we have talk about basics about the JTAG. So I was thinking about explain how the JTAG state machine works will be more helpful for those who new to FPGA. So, before we talk about the state machine, lets see what is the state machine? So, this is the state machine […]

Lets Start Working with FPGA [Part 2]: How JTAG works?

Ok, Last time we have talk about what is a JTAG. This time we are going to talk about how JTAG works? Control JTAG from PC Simply we can use a “JTAG cable” to control a JTAG bus form a PC, it is just a way to control JTAG signals from PC. Normally, JTAG cables […]

Lets Start Working with FPGA [Part 1]: What is JTAG?

Hello everyone, so today I’m going to talk about JTAG. so, what is a JTAG? Well, JTAG is an IEEE standard (1149.1) developed in the 1980s to solve electronic boards manufacturing issues. But now, it is most often used as programming, debug and probing port. So, this is a figure of industrial PCB(printed circuit boards). […]
