combinatorial

!NOTE: This device has outputs that can be put in a high impedance state.
!      Inorder to test the enables (G1bar, G2bar) pullups have to be used
!      on the outputs. Uncomment the two execute statements in the disable
!      unit to test these pins.
!ALSO  Unused inputs can cause problems with this test reliably working if
!      they are left floating.

vector cycle  1u
receive delay 900n

! warning "Pull-ups are required to test high-impedance outputs."
