I am using Cyclone III devices with EPCS16, with quartus 9.1(!!)
I want to know:
Hi Rami Damari,
If you look at AN822 (Table 4 on page 9), the Intel Quartus software support EPCQ-A device starting from version 17.1 and later.
However, EPCQ-A device can be programmed with old JIC files created for EPCS/EPCQ device. Unfortunately, there are some conditions you need to follow in order to program with old JIC file. These are the conditions:
For your case, you are using Quartus 9.1 version and Cyclone III, EPCQ-A device would not support your FPGA and Quartus.
