Logic Navigator^TM for Actel FPGAs
Logic Analyzer and Debug Tool for Actel Programmable Logic

The FS2 Logic Navigator™ is an On-Chip Instrumentation (OCI®) trace and debug tool that provides logic analysis capability to Actel FPGA internal logic. It supports Actel® Flash based FPGAs, including ProASIC and ProASICPLUS, and Antifuse devices (MX, SX, and AX) providing an intuitive and easy way to view internal signals and debug the logic design. It can simultaneously trace and trigger on up to 256 signals in the FPGA fabric with support for up to 4096 total nodes during the debug session. Logic Navigator (on-chip) is a software product that utilizes the Actel FlashPro or FlashPro Lite programmer to interface with the Actel target system.

The Logic Navigator system is highly configurable to allow you to customize and balance features against available logic cells and on-chip resources. You can easily generate the analyzer system logic using the FS2 OCI Generator tool that is included with the Logic Navigator product. OCI Generator automates creation of the OCI and integrates the code into the Verilog or VHDL design files that are then implemented in the FPGA. Logic Navigator is compatible with Actel Libero synthesis, place and route programming design flows for Actel devices. Up to 4096 signals (configured as 16 input sets of 256 channels each) can be defined for triggering and trace, depending on available on-chip logic resources. During the debug session, you may select any one of the input sets for monitoring. The selected channels are fed into the triggering and trace capture system. Input set selection and trigger patterns can be easily selected in the graphical user interface (GUI) or in the Tcl/tk based command line interface. Trace capture results are displayed as a waveform in the GUI or output as text in the console.
