Description
In IP cores that are imported from AMD Vivado™ HLS, the compile_c
command
detects C, C++, and SystemC files and converts those files to RTL for synthesis by
the Vivado Design Suite.
This lets you use Vivado HLS to describe IP cores in a high-level language, like C or C++ rather than RTL.
When HLS-based IP cores are generated, they only deliver the C source. When the HLS-based IP is synthesized, either in the out-of-context flow, or with the top-level design, the compile_c
command launches Vivado HLS to convert the C source files into RTL, and import the resulting RTL sources back into the design prior to synthesis.
compile_c
command is automatically called by the Vivado Design Suite when it encounters IP with C code from the Vivado HLS system. You should not need to manually call this command.Arguments
-force
- (Optional) Force regeneration of the RTL in the HLS-based IP.
-quiet
- (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
-verbose
- (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config
command.
<objects>
- (Required) Specify the IP objects in the current project to convert files from C, C++, or SystemC to RTL code.
Example
The following example gets the C-language files from the specified IP object and converts them to RTL:
compile_c [get_ips instance_name]
