In fact, none of the transistors on the gate array are initially connected at all. Once given a design, the layout software figures out which transistors to con- nect by placing metal connections on top of the die as shown. An unrouted die is processed with all of the layers except for the final metal layers that connect the gates...

SRAM-based FPGAs can also be reprogrammed while in the system, which makes in-field upgrading very easy. Also, SRAM-based FPGAs can be used for reconfigurable computing, a concept whereby computers contain FPGAs and algorithms can be compiled to run in the FPGAs.. That’s because every semiconductor company in the world knows how to make SRAMs. Because an antifuse FPGA is programmed...

An algorithmic model of a circuit can be simulated to test that the basic specification of the design is correct.. Architectural models may be divided into blocks representing PC boards, ASICs, FPGAs, or other major hardware components of the system, but they do not specify how the algorithms are implemented in each particular block. These models of a circuit can...

By placing a synchronizer flip-flop, S1, in front of the logic, the synchronized input, SYNC_IN, will be sampled by only one device, flip-flop FF1, and be interpreted only as a logic 0 or 1. Figure 5.15 Metastability — the problem. Figure 5.16 Metastability — the "solution". including enough synchronizing flip-flops to reduce the probability so that the problem is unlikely...

Because you have designed your chip using top-down methodology, you can take advan- tage of the multilevel simulation that can be achieved using HDLs. Your design will be created first using behavioral models that confirm the general algorithms and architec- ture of the chip. As you refine different behavioral blocks into RTL descrip- tions, you can replace those behavioral blocks...
