I think maybe GP means 'what does it cost to get a simple design on a die say for sake of argument 8xAND', i.e. something very small and simple like that, so that it's all fixed cost.
You'd be correct.
I was asking the question to get a handle on base process pricing and experiences for a design currently utilising 500k LUTs and residing in a fpga. But I didn't want to get too bogged down in details.
Do you still recommend the 74LS30 for that?
No, then you should contact a fab that does shuttle runs and take it from there.
