Version 10.0 Features

SynaptiCAD is proud to release version 10.0 of our product line. Version 10.0 includes the release of a new interactive graphical debugger, BugHunter Pro, and two great new software options - Reactive TestBench Generation and Timing Analysis.


Reactive TestBench Generation Option

The Reactive Test Bench Generation option is available for WaveFormer Pro, VeriLogger Pro, BugHunter Pro and DataSheet Pro to upgrade their native "stimulus" based test bench generation. With Reactive Test Bench Generation, the user can describe more complex test benches that will monitor the results from the model under test (MUT) and create reports of the pass or fail status of the simulation.

  • Draw "expected" waveforms on the Module Under Test (MUT) output ports
  • Add Samples to the waveforms to:
    • watch output during simulation & compare to drawn states
    • react to test results with a variety of actions (pause simulation, report errors/warnings, etc.)
  • Markers can be used to loop over sections of the diagram, call user-written HDL code and wait for activity from the MUT
  • Create "clock-based" or "time-based" test benches.
    • Delay in clock cycles or times, based on the type of test bench being created.
    • Clock-based test benches allow the user to change clock frequency without changing the diagram.
    • Clock-based test benches are required when testing with high-speed "cycle-based" simulators.
  • Setups and Holds generate code to perform checks during simulation
  • Sensitive Edges allow you to specify signal events you want to wait on
  • Ability to insert user HDL code into testbench via Includes, HDL Markers, and User Defined Methods (i.e. tasks/functions)
  • Tutorial on Reactive TestBench Generation features. This tutorial introduces some of the reactive test bench feature set, which is included with TestBencher Pro and can be optionally added to Waveformer Lite, Waveformer Pro, Datasheet Pro, and BugHunter Pro. The tutorial covers creating cycle-based test benches, for-loop markers, bi-directional signals, waiting on events driven by the model under test (MUT), and verifying the output of the MUT


Timing Analysis Option

The Timing Analysis Option is available for VeriLogger Pro, BugHunter Pro, and WaveFormer Lite to upgrade the drawing environment so that delays, samples, and holds will move and monitor waveform transitions. This option essentially changes the timing diagram editing environment so that it becomes a timing diagram editor capable of performing critical path timing analysis.

TestBencher Pro generates test benches from graphical timing diagrams.

  • Project hierarchy tree maintains expansion information when new objects are added to the tree
  • Generate Test Bench on Build Project option automatically updates test bench for changes to timing diagrams each time the project is compiled. This is on by default, but it can be turned off if user wants to temporarily change some of the generated source code manually or to avoid updating the test bench on diagram changes for quicker compiling
  • Added PDF documents to explain the following TestBencher Pro examples in detail: AMBA, PCI, pipelining, uarttest, VME. These can all be found in the {SynaptiCAD Installation Directory}\install\Examples\docs directory

TestBencher Pro includes BugHunter Pro's Graphical Debugger

  • Provides better control of external simulators & compilers
  • Single Step graphical debugging supported for Mentor's ModelSim VHDL and Verilog simulators, Cadence's NC Verilog/VHDL and Verilog XL simulators, and Aldec's ActiveHDL simulators
  • Simulator settings can be defined for diagram simulations independently of project simulations
  • Expanded Project Simulation Properties provides better control over external tools and also provides multiple configurations for defining options for different machines, different simulators, and to create debug versus high speed simulations

Bus-functional Model Code Generation

  • Added two new folders under each transaction diagram in the project window: Included External to Module and Included Internal to Module. These folders allow easy access to user included files and is linked to the Diagram Properties dialog
  • Added Initial Value field for project and diagram variables
  • Test Bench and Transaction Generation Features/Modifications:
    • All Note and Warning messages output by TestBencher Pro during simulation can now be enabled/disabled via two variables: EnableNoteMessages and EnableWarningMessages
    • Enhanced messages generated for Sample Display Message action
    • Added extended comment block at top of generated transactors that summarizes the contents of the transactor
    • Added support for multiple diagram instances in VHDL
  • New Project Generation Settings options:
    • Add timestamp to each file setting (useful if the generated code is versioned & you don't want the generated file to be different just because the time is different)
    • Prefix Generated Files With setting (useful for versioned code for providing keywords to versioning system)
    • Indent Size setting added - affects all generated code in the project
  • New Diagram Settings options:
    • Added Delay After Clock Edge option to Diagram Settings which contains two options: Fixed and As Drawn. If "Fixed" is selected, the user can specify the fixed amount of the delay. This affects code generated for clocked signals
    • Display Applied Inputs verbose option displays the value of transaction inputs in the simulation log file

Features/Improvements for Transaction Parameters

  • New Pipeline Boundary marker type which makes the construction of pipelined transactors much easier and automatic
  • For-Loop Markers in VHDL are now implemented using while loops so that the loop index can be declared as a shared variable and accessed anywhere in the diagram
  • Added FIFO Semaphore feature. Semaphores are created in the Project's Class Library and Variables dialog

Simulation & Library Features

  • Sim Diagram (not Sim Diagram and Project) will now drive Input signals. This allows you to test out simulated signals contained in a transactor before integrating it into the project
  • Added syncad_vhdl_lib and syncad_verilog_lib which contains a collection of base modules that the Testbencher Pro generated code uses. This library needs to be compiled once per installation of TestBencher Pro and is done via the Compile Syncad Libraries button in the Options > Simulator/Compile Settings dialog. Use of these libraries helps speed up the compilation time of individual projects
  • Added new clock models for use in VHDL which are used to more accurately simulate the clocks drawn in TestBencher Pro's transactor diagrams. These are a part of the new syncad_vhdl_lib

All new features in BugHunter Pro, WaveFormer Pro and Timing Diagrammer Pro are in TestBencher Pro.

TestBencher Pro has Timing Analysis, Reactive TestBench Generation and Multiple Diagram Windows built-in.

BugHunter Pro is an interactive graphical debugger for Verilog, VHDL and C++.

  • Graphical Test Bench Generation for quickly testing small modules & doing bottom up testing
  • Stimulus & Results diagram
    • Provide stimulus for simulation
    • View simulation results in a diagram format during & after simulation
  • Manage TestBench interface - easily create a set of regression tests for design
  • Interactive Debugging for Verilog, VHDL and C++ simulators & compilers:
  • Supports all major Verilog & VHDL Simulators
  • The ability to define simulator settings for diagram simulations
  • Project hierarchy tree maintains expansion information when new objects are added to tree
  • Expanded Project Simulation Properties provides better control over external tools and also provides multiple configurations for defining options for different machines, different simulators, and to create debug versus high speed simulations

Step-by-step debugging

  • Time Break Points can be set through the Breakpoint tab in the Report window
  • Source Code Break Points can be set by clicking to the left of a line of source code in an Editor window. They can also be added through the Breakpoint tab in the Report window
  • Step into & over trace debugging
    • Step Into with Trace button sends a message to the Simulation Log tab in the Report window after each step. This lets you quickly inspect the command that was just executed
    • Step Over button does do not step into a function or task but allows the simulation to continue until the next line after a function or task call
  • Break at Time Zero puts the simulator in an interactive mode after compile so that you can give the simulator commands before anything happens in the simulation. It is the equivalent of setting a breakpoint at time zero

Watching Signal & Variable Values

  • Inspect Values window lets you set and inspect register and signal values. You can also view values at previous simulation times
  • Scope buttons, with the capitol S and lower case s, change the scoping level of the values in the Inspect Values window
  • View values in Editor windows by placing the mouse button over signal or variable name in the code
