Coverification speeds soft-core FPGA designs
CoVer is a novel hardware/software coverification platform for FPGA designs using soft-core microprocessors.
The patent is based on automatic conversion of ASIC designs with multiple clock domains and numerous clock-related signals into FPGA clocks and signals, while preserving the original ASIC design functionality in the FPGA architecture.
"With full automation of the clock conversion process, ASIC designers will finally be able to do away with the main source of prototyping errors", stated Dr Stanley Hyduke, President of Aldec.
He added: "Error-free ASIC prototypes will now be done in a fraction of the time it took before".

The patented clock conversion algorithm is based on converting ASIC designs with multiple clock domains into equivalent circuits clocked by a single clock line.
Gated and divided clocks are converted without any restrictions or limitations.
By principle, multiple ASIC clock domains are always successfully converted into the equivalent FPGA circuit.
The resulting FPGA design with only one clock line is free from timing violations, which usually occur while signals are crossing the clock domains.
Also, because the patented algorithm automatically generates a single, low-skew clock line, the newly created FPGA design is free of setup/hold violations and race conditions.
Finally, the clock conversion algorithm supports latches; it eliminates latch-to-flip-flop, flip-flop-to-latch and latch-to-latch timing violations.
All FPGAs have a limited number of clock lines and do not work well with multiple clock circuits.
Conversion to one clock line allows quick implementation of designs in FPGAs without concern about timing issues.
The patented algorithm allows full automation of the design conversion process and the user does not need to enter any constraints or other information to run synthesis.
The clock conversion algorithm is useful for quick timing analysis of the original ASIC design.
If the ASIC design outputs differ from the equivalent outputs of the converted FPGA design, then timing violations are present in the original ASIC.
The ASIC timing violations can be traced by performing static or dynamic timing analysis of the signal lines that produced different waveform signals.
Companies with time-critical ASIC product development schedules will particularly benefit from the new patented ASIC prototyping software product that will be announced in Q3 2006.
