IC library

Ready-made chips, your own subcircuits and your college's shared chips.

Open ICs in the dock to browse chips. The panel has a search box ("Search: 555, NAND, op-amp, a pin…"), a list, a pinout diagram for the chip you select, and a Place button.

Starter chips

The starter set is seven 74HC logic chips in 14-pin packages:

ChipWhat it is
74HC00Quad 2-input NAND
74HC02Quad 2-input NOR
74HC04Hex inverter
74HC08Quad 2-input AND
74HC32Quad 2-input OR
74HC74Dual D flip-flop
74HC86Quad 2-input XOR

Select a chip to see its pinout and a one-line description, then press Place 74HC00 (or whichever chip you chose).

Build your own chip

Build the circuit you want to reuse.
Select its parts and choose Parts, then Create a subcircuit….
Name it and set its pins.
Place it as a Subcircuit instance, or find it under Yours in the ICs panel.

Use Manage subcircuits… to rename or remove the ones you've made. Your chips travel with the project, so they're there when you reopen or share it. Creating subcircuits isn't available in tests.

College library

If your college has shared chips, they appear in the College library group automatically. Students can place them but not change them. They aren't copied into your project's saved data.

Limits

  • A project's chip library is limited in size (about 1 MB).
  • Names in a college library must be unique.
