Technology independent RTL coding

5.2.9. Technology independent RTL coding

Write HDL code in technology independent fasion. This helps reusage of the HDL code for any technology node. Do not hard code logic gates from the technology library unless it is necessary to meet critical timing issues.

 

5.2.10. Pads separate from core logic

Pads are instantiated like any other module instantiation. If design has large number of I/O pads it is recommended to keep the pad instantiations in a separate file. Note that pads are technology dependant and hence the above recommendation!
