Logic Analyzer: eSPI decode, eSPI trigger

  eSPI decode: Software decode for captured eSPI waveforms
  1. Decode Single/Dual/Quad mode trace and protocol data for up to 100MHz signal.
  2. Export raw data for validation.
  3. Provide Bit Field details for Configuration and Status
  4. Provide Virtual Wire / PECI over eSPI / OOB / KBC / EC decodes.
  5. Hide or Show specific commands/data for easy view.

  eSPI trigger: Hardware trigger on specific streaming eSPI command(s) or/and data
  1. Trigger eSPI command or data by 8 states with 2 Timer or 2 Counter conditions
  2. Trigger a DSO by a sync cable to capture the analog waveforms at the same time.
