Hi Bin, Thank you for the clarification and for pointing out the other potential users of this IP. After reconsidering the issue, I realize that my earlier concerns about K230-specific behavior were unfounded. I agree that abstracting this into a generic Synopsys DesignWare APB GPIO model would be a worthwhile approach, and I support moving forward in that direction. Thank you again for your guidance. Best regards, Junze
