about AHB2APB Bridge

[HPC]

Hi,

I am designing an AHB2APB bridge.
I want to know that should the HRESP output of my bridge be held low continuously? Or it can have other value.

Thanks in advance

Usually, you can tie it to "OKAY" all the time, if:
1): The slaves on the APB bus will never generate "error" response (that means every r/w transfer will success). This is usually the digital circuit does.
2): The slaves on the APB bus can response the r/w access quickly enough to met your AHB bus requirement. (this means there is no bus efficient issue, so there is no need for you to use "RETRY" and "SPLIT")
