The Basic Trigger Setup window has three cells that you can configure in a specific row corresponding to a probe:

  1. Operator: This is the comparison operator that you can set to the following values:
    • == (equal)
    • != (not equal)
    • < (less than)
    • <= (less than or equal)
    • > (greater than)
    • >= (greater than or equal)
  2. Radix: This is the radix or base of the Value that you can set to the following values:
    • [B] Binary
    • [H] Hexadecimal
    • [O] Octal
    • [U] Unsigned Decimal
    • [S] Signed Decimal
  3. Value: This is the comparison value that will be compared (using the Operator) with the real-time value on the net(s) in the design that are connected to the probe input of the ILA debug core. Depending on the Radix settings, the Value string is as follows:
    • Binary
      • 0: logical zero
      • 1: logical one
      • X: don't care
      • R: rising or low-to-high transition
      • F: falling or high-to-low transition
      • B: either low-to-high or high-to-low transitions
      • N: no transition (current sample value is the same as the previous value)
    • Hexadecimal
      • X: All bits corresponding to the value string character are "don't care" values
      • 0-9: Values 0 through 9
      • A-F: Values 10 through 15
    • Octal
      • X: All bits corresponding to the value string character are "don't care" values
      • 0-7: Values 0 through 7
    • Unsigned Decimal
      • Any non-negative integer value
    • Signed Decimal
      • Any integer value
