I'm not sure I understand your question.

The simple past just uses a main verb in the past tense. The past tense is formed by adding 'ed', or if it's an irregular verb, you just have to memorize the past tense.

Ex:
You walked to work.
I brought him coffee.
He was late.

The past perfect used the auxiliary verb 'had' plus the past participle of the main verb. The past participle must be memorized, also.

Ex:
You had walked to work.
I had brought him coffee.
He had been late.
