Hi members,
I developed a Spartan-II (xc2s150-5pq208) based card. I also installed Xilinx Flash (xcf01s) there. Unfortunately when I detect these chips through JTAG, I found Xilinx Virtex (XCV150) device instead of Spartan- II (XC2S150). Rest of all is fine..
I have already done the following..
- Supplies are proper.. VCCO is 3.27V and VCCINT is 2.5V
- Decoupling capacitors are there.. 0.1uF, 0.01uF (with most of power pins) and 47uF (with most of IO banks)
Please anyone guide me... where is the mistake..?
I am so grateful to you.
Regards, Mir
