The ic file extension is associated with SPICE (Simulation Program with Integrated Circuit Emphasis), developed by National Instruments Corporation for Microsoft Windows.
These files store initial condition settings for SPICE. The settings are used when the software starts a circuit simulation and needs specified initial values.
Open the ic file with SPICE on Microsoft Windows. The software uses the file as part of its simulation settings rather than as a standalone document.
An ic file is not normally converted to another format. To use the settings in a different SPICE project, recreate or re-enter the initial conditions in SPICE.
