gen_program_header

CodeArtifact

gen_program_header is a function in the riscv_asm_program_gen assembly-program generation flow. It is called by gen_program(), populates the instr_stream string array with program header content, and delegates insertion of the _start section to gen_section("_start", str).

Overview

gen_program_header is part of the riscv_asm_program_gen.sv assembly generation flow used in CHIPS Alliance's open-source riscv-dv random instruction generator for RISC-V processor verification. The surrounding riscv_asm_program_gen class generates complete RISC-V assembly programs, including sections such as initialization routines, instruction sections, data sections, stack sections, page tables, and interrupt/exception handling.

riscv_asm_program_gen member_of The evidence states that riscv_asm_program_gen.sv contains functions that generate the complete assembly program, and describes gen_program_header() as a function called within that class flow.

gen_program called_by The evidence states that gen_program() calls gen_program_header() after directed instruction stream setup.

gen_section calls The evidence states that gen_program_header() calls gen_section("_start", str), which inserts header instructions into instr_stream.
