Click the menu bar Tools -> Options, as shown in Figure 6.5, click OK.Method 1: Simulation based on waveform input Here, use ModelSim to simulate verifing the experiment.
Select the pipeline to speed up the operation, as shown in Figure 6.4.Ĩ×8 multiplier instantiation: reg sys_clk；Ħ.4 Use of ModelSim and the Experiment Verification.Select the multiplication type to be Unsigned.After adding the LPM_MULT IP ( IP Catalog -> Library -> Basic Functions -> Arithmatic -> LPM_MULT) and saving the path, the setting window of the multiplier is popped up, as shown in Figure 6.2, and the two input data is set to eight bits as required.Step 2: The multiplier IP core setting steps are as follows: The value of the switch is used as the first input of the multiplier, the value of the counter is the second input, and the result of the calculation is output. The first step: the establishment of the main program framework module mult_sim ( Only one counter, one PLL and one multiplier are used in the program. ModelSim, different from the previous experiment, when building the project, you need to add the simulation tool to be used in the EDA tool selection window. Our program can be simulated to achieve inspection and error correction. ModelSim is an HDL language simulation software. Since learning uses of the simulation tools and the new IP core, there is no introduction and hardware design part. Observe the calculation results with a four-digit segment display.8×8 multiplier, the first input value is an 8-bit switch, and the second input value is the output of an 8-bit counter.Experiment 6 Use of Multipliers and ModelSim 6.1 Experiment Objective
