what is the difference between same voltage and same temp?

the snapshot is timequest timing model but we find the slow and fast model have same temp and same voltage. so we want to know what is the difference between same voltage and same temp?

Semiconductor chips are subject to variation during fabrication (https://en.wikipedia.org/wiki/Process_variation_(semiconductor)). That means when you purchase multiple units of the same device, some will be slow and some will be fast. To make sure all of them work normally functionally, users will need to ensure timing requirement is met in all timing corners.
