This discussion focuses on importing SPICE models for integrated circuits (ICs) into Multisim, specifically addressing the 74LV4051PW (8:1 MUX). Users express challenges in importing these models and seek guidance on the process. It is confirmed that a .subckt definition is necessary for successful importation, and users are advised to consider whether a full SPICE simulation is required or if a functional/digital level simulation suffices. The conversation emphasizes the importance of understanding the characteristics of the MOSFETs used in the IC for accurate modeling.
PREREQUISITESElectronics engineers, circuit designers, and students involved in circuit simulation and modeling, particularly those using Multisim for integrating SPICE models.
At what level do you want to simulate your circuits? At a functional/digital level, or a full-resolution SPICE simulation?AMRITHAPRIYA K K said:I require many ICs for simulation . For few of them I got spice models but I am not able to import it. One of them is 74LV4051PW(8:1 MUX). Can you provide me with the steps?
Do you have a spice model for that?AMRITHAPRIYA K K said:One of them is 74LV4051PW(8:1 MUX).

Then you don't need a full SPICE model, do you?AMRITHAPRIYA K K said:functional/digital level only
