MARLBORO, Mass. Innoveda Inc. has created an FPGA tool package that integrates the Visual graphical entry HDL tool originally sold by Summit Design with several FPGA offerings originally from Viewlogic.
Innoveda, which was formed earlier this year by the merger of Summit Design and Viewlogic, is leveraging the tool strengths of those two companies to create a sophisticated ensemble for FPGA design, said Philip Lewer, product marketing manager at Innoveda.
"Visual HDL has traditionally been used in the ASIC tool flow, but it is a great tool for FPGA designers in all arenas," said Lewer. "It will allow customers to design at a higher level."
For $15,000, the company's new Innovate FPGA tool suite includes Innoveda's Visual HDL, IntelliFlow and Fusion tools and is packaged with Synopsys Inc.'s FPGA Express. The tool also works with Synplicity Inc.'s Synplify tool, though users must license Synplify directly from Synplicity.
In the Innoveda flow, designers will use Visual HDL to graphically capture finite state machines, block diagrams, truth tables and flow charts; then the tool automatically generates optimized HDL code for logic synthesis tools.
Lewer said a new feature in Innovate is the ability to quickly go from graphics into FPGA implementation flows by launching the IntelliFlow flow manager, which unifies functional simulation, synthesis, place and route, and verification under a single user interface, regardless of target FPGA vendor or family.
Lewer said the tool presents easy-to-understand design flows for FPGA design. For simulation and verification, IntelliFlow uses the Fusion tool to functionally simulate the VHDL or Verilog generated by Visual HDL and verify an FPGA's timing and functionality after place and route. Fusion includes the Fusion/SpeedWave VHDL simulator and Fusion/VCS Express Verilog simulator, but users can also license the simulator in Visual HDL for an additional price.
IntelliFlow automatically passes the code provided by Visual HDL into synthesis for analysis, elaboration and optimization.
Once synthesis is completed, IntelliFlow runs the FPGA vendor-provided place and route software on the synthesized netlist and then generates a PC board symbol for instantiation onto a PC board-level schematic.
Innovate also provides a seamless link from design capture into FPGA logic synthesis via IntelliFlow, said Lewer. From IntelliFlow, users can choose between the Synplify or FPGA Express synthesis engines.
