New Features in SynaptiCAD Tool Suite v15.0

The mouse tooltip now displays the next and previous states of bus segments when the mouse hovers over a state transition. This feature can be disabled by unchecking the View > Show State at Cursor menu. See Section 1.5 Measuring Time and State values for more techniques on viewing states.

Tool tip shows bus states on either side of a transition

Bus segments automatically show partial extended state data when the segment is too small to fit the entire state within the segment. Two trailing dots indicate the value is only partially shown.

Markers labels "float" at the top of timing diagram windows so that as you scroll vertically through the diagram you can still see the marker display label (Section 6.5 Marker Lines).
Hover over a Group Bus name to display member signals of the bus in a tooltip (Section 3.2 Group Buses).

Group Bus tool tip shows all the member signal names

Japanese fonts are supported in the timing diagram window

User-defined radices can now be saved in filter files, so you can store your own customized radix for viewing the imported waveform data from a VCD or other waveform source file (see Section 11.2 Import General Instructions ).

New Python-based Waveform Block Equations can be edited after a waveform is created, unlike the older State and Waveform equations. These are especially useful for analog waveforms which can be difficult to get right on the first try. See Section 8.2 Waveform Equation Blocks for editable Analog waveforms for information on how to create waveform equation blocks.

Waveform Block Equation Definition

There is a special view mode that highlights all the Waveform Block Equations in a diagram with blue rectangles so that you can easily identify and edit the waveform equation blocks. Double clicking on a waveform block in this mode will automatically open a dialog to edit the equation block. A block can be moved by clicking and dragging the edge just preceding the block.

Special View draws blue boxes around Waveform Block Equations

The Auto Save for Recovery feature temporarily saves timing diagrams at specified intervals so that data can be recovered in the event of a premature termination of the program (e.g. in case of a power failure).
Delay correlation information has been added to the Timing Analysis Report. This report is generated when a diagram is saved with a file type of Timing Analysis Report. The report is saved to a file and also displayed in the Report window.

Timing Analysis report can show delay correlation data

WaveFormer Pro can read files generated by the MSO4000, MSO3000, and MSO2000 series mixed-signal oscilloscopes from Tektronix (see Section 11.14 Tektronix Logic Analyzer & Oscilloscope - Import ).
It is now ten times faster to drag-and-drop all of the transitions on one signal by holding down the "1" and "2" number keys while dragging. Holding down just the "1" key moves all the edges to the left, and the "2" key moves all the right.
Users can now manually edit TIM files in a text editor.
New icons with little boxes around them indicate that a signal is a "compare" signal.

Compare signals are marked with a special icon

Integration with TI's SystemC-based High End Timer simulator. This can be downloaded directly from the TI web site at http://focus.ti.com/docs/toolsw/folders/print/het_ide.html .
Improved HTML-based help for UNIX.

Added support for 64-bit simulation under 64-bit Windows operating systems. To compile 64-bit simulations you also need to install the free Windows SDK 7 from Microsoft. In the BugHunter & VeriLogger Manual see Section 5.1 VeriLogger Extreme tools: Simx and Simxloader for downloading details.
Support for Xilinx SecureIP models.
Cycle-based and non-blocking assignment optimizations result in faster simulation times (e.g. 8x faster on OpenCores ac97 benchmark).
Faster simulation of timing checks.
Reduced memory usage by over 4x for large designs.
Improved code generation results in smaller simulator executables and faster simulation build times.
Faster dependency checking during simulation rebuilds.
Enhanced PLI 1.0 and 2.0 support (all VPI and ACC functions now supported except put_delays/attribute functions).
Support -g/-G/+defparam options to override parameter values from the command line. In the BugHunter & VeriLogger Manual see Section 5.7 Simx Override Parameter Values Options.
Internally tested against Actel and Altera IP Cores.

NEW Schematic Display using BugHunter Pro and GOF. In the BugHunter & VeriLogger Manual see Chapter 10: Schematic Viewing of Gate Level Designs.
Open Gates-on-the-Fly schematic windows from components in BugHunter's hierarchy window to analyze gate-level designs.

Gof can show a schematic from BugHunter Project window

Double click in the new scope column of a Show Driver window navigates to the scope instance. In the BugHunter & VeriLogger Manual see Section 2.5 Find Drivers.
Change driver signal values from a Show Driver window.
Watched signals add after the last selected signal (same behavior as when pressing "Add Signal" button). In the BugHunter & VeriLogger Manual see Section 2.2 Watching Signal and Component Waveforms.

New -v95 and -v2001 options to specify style of Verilog code to translate to.
The No_Component_Check is now turned on by default when translators are executed from the BugHunter GUI. This allows translations to proceed when not all module or entity definitions have been parsed by the translator. This is useful when translating files individually inside the BugHunter GUI. In the BugHunter & VeriLogger Manual see Section 9.2 VHDL2Verilog Translation Options.
VHDL2Verilog supports constants defined using record types.
Many bug fixes.

GOF now supports 64-bit Linux operating systems.
New read_file api can import static timing analyzer data.
New fix_setup and fix_hold API calls for automatically fixing setup and hold violations detected by static timing analyzers.

Added API functions for controlling signal and marker color, setting marker type, and get and set of tooltip display.
New syncadlauncher dll allows a third party application to launch the syncad GUI and perform basic control of syncad.exe without including a CORBA ORB.
