Portfolio News CriticalBlue integrates with Synopsys 21 January 2005 EDA start-up CriticalBlue said it has completed a project that saw its embedded processor development tools integrated with Synopsys' hardware development flow. CriticalBlue's Cascade tool was used to explore the architecture of the system and produce synthesisable RTL for a co-processor. Design Compiler and VCS from Synopsys were used take the logical design to gates. "Synopsys has a long history of supporting emerging EDA companies who provide complementary parts of the design flow. Our customers expect us to enable a degree of validation of these new tools with respect to our trusted flows and we are happy to support this activity," said Karen Bartleson, director of interoperability at Synopsys. The project, for an unnamed firm, was for an error correction circuit used in wireless comms. Source code, aimed at an ARM processor, was profiled by Cascade which produced a choice of architectures. Designers could trade-off gate count and performance before choosing the most suitable co-processor to run parts of the code. The resulting system is aimed at 0.13µm technology. Cascade not only produces the architecture and co-processor RTL, but also microcode and the testbench for verification. "The purpose of validating the flow through the Synopsys RTL implementation flow was to verify the interoperability of the RTL code that Cascade generates and ensure the gate count and performance goal are met," said David Stewart, CEO of CriticalBlue.
