Hi
early beta version is available for immediate downloads
this version only supports Xilinx Cable III and Spartan 3 family (all devices) there are several limitations some jtag chain configuration may cause problems. Support for other FPGA (also Altera) will be added in the next releases.
There is no info needed about your FPGA board and no ref. clock required, the application configures your FPGA to be a frequency meter - all external signal connected to the global clock inputs can be measured.
