3.7.4 Tri0 and Tri1 Nets

Frm:ieee Std 1364?-2001, IEEE standard Verilog? Hardware Description Language

The Tri0 and Tri1 nets model nets with resistive pulldown and resistive pullup devices on them. When no driver drives a tri0 net, it value is 0. When no driver drives a tri1 net, it value is 1. The strength of this value is a pull. See Clause 7 for a description of strength modeling.

A tri0 net is equivalent to a wire net with a continuous 0 value of the pull strength driving it. A tri1 net is equivalent to a wire net with a continuous 1 value of the pull strength driving it.

A truth table for Tri0 are shown in table 6. A truth table for TRI1 are shown in table 7.
