RE: VIO pin connection

[Raj Gandhi <raj.gandhi@qlogic.com>]

 Let me restate my original question.

  Is it Ok to connect VIO pins of a 3.3v ASIC
  that has 5v input tolerant PCI pads (the ASIC
  supports 3.3v signaling and uses 5v for input
  clamping) to connect to +5v supply directly
  instead of VIO pins of a PCI connector.

  In 3.3v environment, the VIO is 3.3v and inputs
  are clamped to 3.3v. In 5v environment, the VIO
  is at 5v and the inputs are clamped to 5v.

  Are there any issues if we always clamp inputs
  to 5v by connecting VIO of an ASIC to 5v rail
  instead of VIO.

  Thanks
