As a beginner to the world of Nios I'm wondering how this component (enhancement to the Altera UART) has been developed.
I read chapter 10 "Developing Components for SOPC Builder" found in the Quartus II Handbook which shows how to develop custom peripherals based on HDL files. When looking into the attached ZIP file, all I can find are some C and Perl files.
Was this component developed in VHDL and exported to Perl or were all of the enhancements directly added into the Perl script? Can anybody point me to literature that describes how I can enhance an arbitrary component originally created by Altera?
Thanks,
Markus
