ZeBu Features Combinational Signal Access

EVE has enhanced the design debugging capabilities of their ZeBu (for Zero Bugs) emulation platform. ZeBu now features Combinational Signal Access (CSA), which enables engineers to dynamically generate complete waveforms of designs. Combinational Signal Access improves productivity and lowers the cost of ownership. CSA comes as a standard component to the ZeBu family. It is available now and, initially, works with zFast, ZeBu Fast Synthesis used with ZeBu emulation systems.

Combinational Signal Access

  • ZeBu users can dynamically generate complete waveforms of their design
  • Values of any register transfer level (RTL) net, register or memory in the design are available quickly
  • Unlimited trace depth and without embedding instrumentation or recompiling the design
  • Tracing a design bug in large designs of hundreds of millions of ASIC-equivalent gates is no longer a tedious, uncertain and, ineffective exercise
  • Design bugs can be pinpointed in just a few hours, if not minutes, on the largest designs
  • CSA works in one of two modes:
    • On-line, when waveforms are generated while the model is running on the emulator
    • Off-line, when waveforms are generated after the emulation run, enabling the emulator to be used for other applications
  • Off-line waveform generation process can be done on the user’s computer and accelerated for very large designs through a proprietary multicore technology
  • CSA is a standard component to the ZeBu family
  • Currently works with zFast, ZeBu Fast Synthesis used with ZeBu emulation systems
