XFLOW Overview
XFLOW is a command line program that automates Xilinx synthesis, implementation, and simulation flows. XFLOW reads a design file as input as well as a flow file and an option file. Xilinx provides a default set of flow files that automate which Xilinx programs are run to achieve a specific design flow. For example, a flow file can specify that NGDBuild, MAP, PAR, and TRACE are run to achieve an implementation flow for an FPGA. You can use the default set of flow files as is, or you can customize them. See "XFLOW Flow Types" and "Flow Files" for more information. Option files specify which command line options are run for each of the programs listed in the flow file. You can use the default set of option files provided by Xilinx, or you can create your own option files. See "XFLOW Options" for more information.
The following figure shows the inputs and the possible outputs of the XFLOW program. The output files depend on the flow you run.
