From: gopal_amlekar on 3 Feb 2010 03:40 Hello, Few days back, I got a good help from this forum about CPLD programming. I have succeded in making my own design based on a microcontroller to configure a spartan 2 as well as to program XC95108 CPLD. Now I am moving to Spartan 3 and struggling with it. A very good document from Xilinx about Spartan 2 configuration is XAPP188 (Specifically table 7 on page 11) which lists steps to be taken while configuring Spartan 2. I did not find such clear information about Spartan 3. Does anyone know more details about the steps for spartan 3? I have already referred to their Spartan 3 configuration guide UG332 but it is slightly confusing. I also tried the way XC3Sprog is implemented but it did not work. Please let me know if you know anything about it. I can share information about spartan2 and xc95... Thanks and regards, --------------------------------------- Posted through http://www.FPGARelated.com

I got it. Spartan 3 needs a Jprogram instruction before config_in instruction. Spartan 3 has a 6 bit IR Vs 5 bit IR of Spartan 2. Rest of the things are almost similar or same.
