The designed ICs are widely used in analog and digital electronics and form the backbone of many practical applications.

Purpose

To provide ready-to-use subcircuit files for the following ICs in eSim:

  • LM3914 (Dot/Bar Display Driver)
  • L298N (Dual Full-Bridge Motor Driver)
  • CD4099B (8-Bit Addressable Latch)
  • CD4016B (Quad Bilateral Switch)
  • MM74C923 (20-Key Keyboard Encoder)
  • CD4026B (Decade Counter with 7-Segment Display Driver)
  • CD4089B (Binary Rate Multiplier)
  • CD4029B (Presettable Up/Down Counter)
  • MC14532B (Priority Encoder)

Approach

For each IC, the schematic was designed in eSim using KiCad. ERC was performed to check for errors. The netlist was generated and converted from KiCad to NgSpice format with the required component values assigned. The input/output waveforms were then verified against the corresponding datasheet and functional behavior to ensure correct operation.
