impulse VP

impulse Workbench Extension
Virtual prototyping has been used in several forms to increase confidence in product design or function. Once the system behaviour and an associated test environment are captured in SystemC, it is possible to reuse that environment as a reference test platform throughout the system implementation work.

SystemC is a set of C++ classes and macros which provide an event-driven simulation interface.

The VP extension comprises the TAB reader (Analogue Tabular Format) used in SystemC AMS systems and the SCV reader for the textual SystemC TLM-2 transaction database.

The VCD format is already supported by the impulse core features.

impulse VP is available with impulse 2.0.x.

Debug and Understand SystemC Implementations

Navigate through VCD hierarchies; filter and search for incidents.

Visualize the TLM-2 Transaction Flow

Display transaction graphs and navigate forwards and backwards.

Extract and Visualize Performance Figures

Display VCD wave forms together with transaction plots. Navigate through the graph of the relationship and display transactions in tabular form.

TAB Reader

This format is used in SystemC AMS systems. The format uses pure text and stores the numeric values in columns similar to CSV.

SCV READER (beta)

With the SCV reader, you can read System-C transaction text database traces. An SCV text database file stores transaction traces in plain text format.

Simulation

Electronic circuit simulation uses mathematical models to replicate the behaviour of an actual electronic device or circuit. The output of these simulations can be analysed using impulse in many ways. Analysed simulations of analogue and digital systems include: systemC (VCD, TAB, SCV); Verilog, VHDL (VCD, eVCD, LXT2, VZT, FST) and Spice (HSpice, NanoSim, Spice3).
