The Hardware Description language file is obtained by pressing Generate HDL in the bottom right corner of the
window. A new window opens, - Generation . In this window under Synthesis, select via Dropdown Menu in which
Hardware Language your HDL will be created, Verilog or VHDL, and check Create block symbole file (.bsf) and
uncheck Create timing and resource estimate... .
Press in the bottom left Generate and the saving dialogue opens, reminding to save the design. Name the file, this
guide designates the file PlatformEditorHPS.qsys , press Save and wait until the design is saved. The window shows
the
message - Save System: Completed successfully.
