Incisive is a suite of tools from Cadence Design Systems related to the design and verification of ASICs, SoCs, and FPGAs. Incisive is commonly referred to by the name NCSim in reference to the core simulation engine. In the late 1990s, the tool suite was known as ldv (logic design and verification).

Depending on the design requirements, Incisive has many different bundling options of the following tools:

Tool command description
NC Verilog ncvlog Compiler for Verilog 95, Verilog 2001 and SystemVerilog
NC VHDL ncvhdl Compiler for VHDL 87, VHDL 93
NC SystemC ncsc Compiler for SystemC
NC Elaborator ncelab Unified linker / elaborator for Verilog, VHDL, and SystemC libraries. Generates a simulation object file referred to as a snapshot image.
NC Sim ncsim Unified simulation engine for Verilog, VHDL, and SystemC. Loads snapshot images generated by NC Elaborator. This tool can be run in GUI mode or batch command-line mode. In GUI mode, ncsim is similar to the debug features of ModelSim's vsim.
Sim Vision simvision A standalone graphical waveform viewer and netlist tracer. This is very similar to Novas Software's Debussy.
