The designed Integrated Circuits are very popular and these are used in our everyday life. These all are the backbone of electronics application.

Purpose
The main motive is to make easier of implementation complex ICs with these basic ICs in eSim.
The list of ICs present in this pull request are as follows:

  1. SN74LS461
  2. SN74LS498
  3. SN74LS451
  4. SN74LS247
  5. SN74S268
  6. SN74278
  7. SN74LS295B
  8. SN74AS303
  9. SN74AS304
  10. SN74AS305
  11. SN74LS353
  12. SN74S532
  13. SN74S536

Approach
For designing the IC in eSim first we need to make schematic of the IC. Then annotate the components in the schematic. After that make a symbol of the respective IC. Create a netlist of that file. After that convert KiCad to NgSpice with giving the component values. Now we are ready to check the input, output plots for analysis of the IC.
