SUMMARY

The discussion centers on adding a PROM to a Spartan-II FPGA board from Digilent, which lacks a configuration PROM. The user plans to utilize the VC18V02VQ44C PROM and intends to program it using JTag, followed by configuring the FPGA with Master Serial. The required connections include four JTag pins and four pins for the serial connection, indicating a straightforward setup process. Participants confirm that hooking up a configuration PROM has remained relatively simple over the years.

PREREQUISITES
  • Understanding of Spartan-II FPGA architecture
  • Familiarity with VC18V02VQ44C PROM specifications
  • Knowledge of JTag programming techniques
  • Experience with Master Serial configuration methods
NEXT STEPS
  • Research the VC18V02VQ44C PROM datasheet for detailed specifications
  • Learn about JTag programming for Spartan-II FPGAs
  • Explore Master Serial configuration procedures for FPGAs
  • Investigate common pitfalls when integrating PROMs with FPGAs
USEFUL FOR

FPGA developers, hardware engineers, and hobbyists working on projects involving Spartan-II FPGAs and configuration PROM integration.

Hi all,
I'm new to the forum and would like to say hi to everyone.
I'm currently working on a personal project that is as follow: I have a spartan-II FPGA that's already placed down on to a board by Digilent. This board does not come with a configuration prom. My goal is to add a prom to it. I have done some reading and found out that the VC18V02VQ44c is the one I'm going to use. I will use JTag to program the prom and then use Master Serial to configure my FPGA. The circuitry shows that I only need the 4 JTag pins, and then the 4 different pins for the serial connection. This seems way too simple. I'm wondering if anyone is familiar with this stuff and there is anything I should watch out for.

Thank you

LT

It's probably 20 years since I did FPGAs with configuration proms.
As I recall it was fairly simple to hook one up.
Doubt it has gotten more complex.

Err, well except for the programming :smile:
