Sample behavioral waveforms for design file sin_rom.vThe following waveforms show the behavior of altsyncram megafunction for the chosen set of parameters in design sin_rom.v. For the purpose of this simulation, the contents of the memory at the start of the sample waveforms is assumed to be ( 3F0, 3F1, 3F2, 3F3, ...). The design sin_rom.v has one read port. The read port has 1024 words of 10 bits each. The output of the read port is unregistered. Fig. 1 : Wave showing read operation. The above waveform shows the behavior of the design under normal read conditions. The read happens at the rising edge of the enabled clock cycle. The output from the RAM is undefined until

包含一个ALU，实现斐波那契数列的计算。1.接受两个6位二进制输入。2.通过手动输入的时钟驱动每个周期进行一次计算。3.结果输出到led灯（使用NEXYS4开发板）(Including an ALU to realize the calculation of Fibonacci sequence. 1. Accept two 6-bit binary inputs. 2. Each cycle is driven by a clock input manually. 3. Output to LED lamp (using NEXYS4 development board))
