Table 5–1. nios2-c2h-generate-makefile Command Line Arguments (Part 2 of 2)
Argument Name
--analyze_only
--use_existing_accelerators
Meaning
Disables hardware generation, SOPC Builder system
generation, and Quartus II compilation for all
accelerators in the application. Building the project with
this option only updates the report files. Defaults to 0.
Disables all hardware generation steps. The build
behaves as if c2h.mk did not exist, with the exception
of possible accelerator linking as specified in the
--accelerator option. Defaults to 0.
Example 5–1 shows a typical nios2-c2h-generate-makefile command
line.

You must use the --c2h flag when calling
nios2-app-generate-makefile in order to make your application
with C2H. This flag causes the static C2H make rules to be
included in your application makefile. These rules in turn
include the c2h.mk fragment generated by this command.

C2H
Performance
Metrics
The C2H Compiler produces a detailed report during software
compilation. This report shows hardware structure, resource usage, and
throughput. Using the build report you can view the resource usage and
scheduling information for each accelerated function.
