Q.5. What parameters to be consider while identifying the FPGA? [2]
Answer
- Logic capacity: number of available logic elements/lookup tables (LUTs) and flip-flops, determining the maximum design size the FPGA can implement.
- I/O count and I/O standards supported (voltage levels, differential signaling capability), determining how many external signals the device can interface with.
- Speed grade: maximum achievable clock frequency and internal propagation delay characteristics for a given process/die.
- Available embedded hard blocks: dedicated multiplier/DSP blocks, block RAM (BRAM), embedded processor cores, high-speed serial transceivers.
- Power consumption (static and dynamic), package type/size, and unit cost, all of which must be matched to the specific target application's budget, thermal, and form-factor constraints.
