1. Explain the trade-offs between using a transmission gate or a tristate buffer to implement an FPGA routing block.
2. A fab house has a 180 nm process with a $500 cost per processed 8-inch wafer. If you do the design yourself using open-source tools and the mask cost is $250K, estimate the market size required to obtain 50% margin on a chip that is 3 mm on a side.
