Altera quartus ii output pins stuck as vcc or grd

#Altera quartus ii output pins stuck as vcc or grd serial

I donРІР‚в„ўt even need to keep these boards, I just need to use them briefly as a proof-of-concept. Stretch goals involve getting a massive FPGA to do a lot more with, but those can start to run upwards of $150 just for the chip alone. IРІР‚в„ўd really like to get into low-level optimization. After I do that with the first iteration, I can write a concurrent version, benchmark it, and start tweaking. My goal right now is to, without spending a whole lot of money, to get a development board, or even a bare FPGA on a breakout board with at least 15,000 slices so that I can benchmark this implementation of the algorithm. For further reference, a Papillio Pro, which is very popular right now, uses a version of the Spartan 6 family that has about 9,000 slices. It takes up about 12,000 logical slices, and the Spartan 3E version I have only has about 2,000. Unfortunately, this code, which is the absolute simplest building block of the final project is about 600% too large for my dev board.

IРІР‚в„ўve updated the current code, here, consisting of the parallel behavioral SHA1 implementation, a serial input wrapper that parallelizes the data and acts as an interface, a simulation testbench, and a physical testbench specific to my board. The FPGA kit I have is the Digilent Basys2, and it uses a Xilinx Spartan 3E chip. The end-goal is to eventually integrate that into a PCI-E card, but weРІР‚в„ўll see how that works out. Recently, I got given an FPGA development kit to continue working on myР’В SHA1 system.
