I am implementing an 80000 Element Shift register to be used as a very long (1Sec) digital delay generator. (Yes, its that big). It is clocked at 80kHz.
Its a very simple design, just an ordinary shifter register with 80k elements. It is being implemented in a V2Pro (Digilent XUP Board).
I have simulated the design and it works OK. I am now trying to synthesize the design and it is taking a *VERY* long time. I tried to synthesize on my PC (P4 3.2GHz, 1G Ram) when I left work last night. It failed 5 hours later with an out of memory error. I am now trying on a Xeon Work station with 3GB of RAM.
Any pointers on how to make this synthesize faster?
What kind of machines are people using out there to synthesize large designs?
