LogiCORE CAM v5.1 - Does CAM v5.1 support Virtex-5, Spartan-3E, or Spartan-3A?


When the ISE Project or CORE Generator project option is set to Virtex-5, Spartan-3E, or Spartan-3A, the CAM Core is grayed out, indicating that they are not supported.

When will CAM Core support Virtex-5, Spartan-3E, or Spartan-3A?


Currently, CAM Core does not support these architectures. The CAM Core is being updated in Q3CY2008 to support Virtex-5. The resource utilization for the Virtex-5 devices will be similar to current resource utilization in the Virtex-4.

The FPGA fabric for the Spartan-3 is the same for Spartan-3E and Spartan-3A. To use the core for Spartan-3E or Spartan-3A, follow these steps:

1. Change the device for your ISE project to Spartan-3.
2. Select "Add a New Source" (to your ISE project) and select CORE Generator IP.
3. Run the CORE Generator GUI and generate the core.
4. Change the device for your ISE project back to Spartan-3E.
5. Instantiate the core in your top-level source.
6. If the core has to be reparameterized, repeat steps 1 through 4.

Until the updated core is released, to target a Virtex-5 device, generate one for Virtex-4 using the procedure described above.
