Hi Hugo Elias,
You can view the Verilog source file of the UDB based components from the CyComponentLibrary.Lib.
You can access this from your installation folder. In my case, the location turns out to be
C:\Program Files\Cypress\PSoC Creator\2.0\PSoC Creator\psoc\content\CyComponentLibrary\CyComponentLibrary.cylib
A word of caution! The C files, Header files and the Verilog files if manipulated here will change forever. The change done, if any, will reflect in the Creator generated files. However, you can view the Verilog file to understand its implementation.
Hello Hugo Elias,
As far as I know, There is also a * .v file generated in codegentemp folder that contains the verilog code generated.
