Tcl script error

--- Quote Start ---

Hi:

I am new to Tcl script. I download a simple program from the website, and copy it onto the Tcl script, and try to compile it.

It's just a one line code

puts "hello world"

However, I constantly getting a compilation error of Top-level design entity is undefined

don't know why

Thanks

Hi,

TCL is not a hardware description language like Verilog or VHDL. It is used for e.g. to automate flows ...

Kind regards
