opcode::byte_pack()

CodeArtifact WIKI v1 · 5/28/2026

opcode::byte_pack() is a class method identified in an opcode/instruction transaction model for constrained-random microprocessor verification. The provided evidence describes it as the method responsible for packing an instruction, alongside opcode::psdisplay() for display.

Overview

opcode::byte_pack() is cited as one of the class methods associated with the opcode class in a constrained-random verification model for microprocessors. In the referenced transaction-class discussion, class methods are described as the third component of the transaction class, following properties and constraints.

Purpose

The method is described as the packing method for an instruction. It is mentioned together with opcode::psdisplay(), which is described as a display method. The source states that these two methods are examples of class methods in the opcode class and that Figure 6 shows their bodies in the instruction-class context.

Verification-model context

The surrounding model uses opcode objects and constraints to represent processor instruction rules, such as slot restrictions and illegal-opcode generation for exception testing. Within that model, byte_pack() belongs to the method layer of the transaction/instruction representation, where it provides instruction packing functionality.

Related APIs

  • opcode::psdisplay() — mentioned alongside opcode::byte_pack() as the corresponding display method.

Notes

The available evidence identifies the role of opcode::byte_pack() but does not provide its implementation body or exact packed byte layout. Any details about field ordering, endianness, return type, or encoding format would require additional source evidence.
