Spartan 3 FPGA XC3S200 pins configration

[ashad]

Hi,

I am facing problem in defining the Pin assignments of XC3S200 TQ144 FPGA. I am using ISE8.1i and when i opened Assign package pins then one window opens and it consist the detial package diagram.

when i tried to enter the pin names according to datasheet the software not allow us to enter that names

i need help to rectify this problem

Hi,

I use FT256 and ISE9.1i. Why don't you try upgrading your software?

 

[ashad]

let me explain first.

In ISE 8.1i we have following software window opens. when we click on Assign Pin contrains



when we click on the Design object list



in this how i can enter the pin name ... like i want to give buzzer pin in TQ144 package it is P124, following is the complete name from datasheet

Bank 1
Pin name: IO_L32P_1/GCLK4
pin number: P124
Type: GCLK

please help me to enter these informations in to the follwoing window

You are pretty much close to successful pin assignments what problem you are facing?
In the second picture that you have uploaded, at this place you have to enter the pin number (P124 in your case) in the LOC column in buzz signal row.(enter the number with latter 'P' and without space)

Have you said Yes when ISE asks you to whether it should include a UCF file in project?

another way to enter the pi assignments is add a TXT file with UCF extension and pic assignments using below syntax.

NET 'signal_name' LOC = 'pin_number' ;

I appreciate your kind reply... its works
