Having been involved with CPU emulation in the past a couple of comments: 1. It's not just a single FPGA but a large box full of them. for example: https://www.synopsys.com/verification/emulation/zebu-server.... 2. Software models are employed for parts of the system (For example, the southbridge and all the peripherals connected to it are generally a software model which communicates with the hardware emulated portion in the FPGA via a PCIe model which is partly in hardware and partly in software.) This saves a lot of gates in the FPGA - those parts have already been well tested anyway so no need to put them into the hardware emulation. |
