Calterm (California Terminal) is a command-line software environment used for digital design, specifically for and testing of electronic circuits (often at the gate or transistor level). It’s a tool for engineers working with hardware description languages (like Verilog or VHDL) or netlists.
Note: Calterm 5 is a proprietary tool. Access requires a license from ETAS and is typically restricted to automotive OEMs and Tier 1 suppliers.
