Re: Part IV: Applications of PLCs & PACs

Someone said "I'm still unclear as to why one would use FPGAs to emulate SoC when the SoC already exists in hardware"

I think it's more a case of when you are designing a new PLC or PAC or SBC for an industrial control application -- if there's already an exuisting SoC (ASIC / ASSP / whatever) that does everything you want then you woudl use it. But if the existing SoC doesn;t do what you want ... it will cost millions of dollars and at least 18 months to develop a new one -- or you can get an off-the-shelf FPGA and program it to do whatever you want it to do...
