7 General Properties

7.1 FPGA Mounted on SMT338-VP

All FPGA interfaces on the SMT338-VP require 508 IOs. The following table is a
summary of the amount of IOs available on Xilinx Virtex-II Pro devices.

Table 6. Virtex-II Pro IO Count.

By default all SMT338-VPs are assembled with VP30 devices. The example firmware
is also for a VP30 FPGA. If a VP7 is mounted some of the SHB interface IOs and the
DDR SDRAM memory interface will be lost.

7.2 Design Resource Usage

The following table is a summary of the FPGA resources used by the demo design
that comes with the SMT381-VP (compiled for a VP30 device).
