SAN JOSE, CALIF. -- October 29, 2012 -- Forte Design Systems™, a leading provider of
software products that enable design at a higher level of abstraction and improve design
results, today announced immediate availability of the latest version of its Cynthesizer™
SystemC high-level synthesis (HLS).
Enhancements, including increases to Cynthesizer's performance and capacity, have been
made across the entire tool suite to enable designs to be done faster and with better results.
The latest features include new modeling style support, expanded optimization and analysis
capabilities, integration with third-party tools and improvements to CynWare™ intellectual
property (IP) cores.
"We continue to focus on delivering high-value synthesis software driven by customer needs,"
states Brett Cline, Forte's vice president of marketing and sales. "Cynthesizer 4.3 provides
significant improvements in power results and ease of use while expanding our leading CynWare
IP library, allowing design teams to quickly adopt high-level synthesis and get great results."
Cynthesizer 4.3 has a number of new features to make it easier to model designs and quickly
synthesize to the register transfer level (RTL) with great results. For instance, Cynthesizer
now supports the synthesis of the standard C++ math library "<complex>" in addition to
the CynWare fixed point data types. This modeling technique maintains precision throughout
complex computations in the high-level SystemC design and creates optimized RTL code through
the HLS process. Cynthesizer 4.3 adds support for asynchronous zero-latency memories in
addition to the extensive memory capabilities built into the product.
The use of C++ templates and virtual functions has been expanded for defining module structure
and behavior to allow users to express design intent at a higher level, reducing the amount
of code required and increasing reusability. Cynthesizer supports the use of the standard math
libraries with C/C++ and SystemC datatypes.
Improvements have been made to the Cynthesizer Workbench™ (CynthWB) environment, including
formatting and filtering of tabular reports and the ability to link objects to the call stack
to improve debugging and optimizing of the design. Support has been added for asynchronous external
memories, along with variable accesses to arrays of external memories, register banks and memories
to support more design styles and provide better results. Large projects will load quickly in
CynthWB and navigation through analysis data is faster. The layout for analyzing synthesis results
has been improved, and an analysis capability that compares quality of results (QoR) of two selected
cynthConfigs is included.
Forte's CynWare IP library and CynWare Interface Generator™ have been updated to improve
quality of results and usability. In a power saving move, the CynWare Line Buffer IP interface now
allows memory reads to be avoided for unneeded rows or columns. To improve performance and prevent
avoidable pipeline stalls, CynWare FIFOs implemented with single-ported memories have an extra buffer
register to decouple the synthesized design from the FIFOs internal read-write cadence.
In keeping with a commitment to delivering a seamless integration with downstream design tools, Forte
integrated Cynthesizer with the Cadence® Incisive® Enterprise Simulator and the SimVision
debugging environment, and Oasys Design Systems' RealTime Designer™ to link high-level synthesis
to chip synthesis.
Finally, Cynthesizer now supports mapping arrays in a design to either a flattened set of registers or
a memory, and maps arrays to a register bank for improved capacity and runtime. Designs with large register
banks can be mapped directly to a register bank instead of flattening the array.
The latest version Cynthesizer is shipping now.
