using internal POR

Hi all. I'm new to all this FPGA stuff. Recently bought the Xilinx
Spartan-3 starter kit (now I regret not waiting 2 months for the newer
kit that includes way more for just an extra $50).
Anyways, I'm new to designs in VHDL. I have a background on
microcontrollers (Microchip) but this is so different I feel lost
sometimes.

My question is, I implemented a PS/2 mouse interface from
opencores.org. This needs a reset signal sometime. If I set this signal
to either 0 or 1, the circuit does not work. What I did was keep the
circuit in reset until the clock counter reaches a certain value, and
then release the reset from this module. This works but it seems kind
of nasty. Is there a nicer way to do this?

Hernan
