Tina, diode model

Here is a kind of diode model in Tina. I'm confused that:

1) what is the meaning of IBV? Is it the current when the diode is applied to the reverse volage BV?

2) what is the meaning of VR? Actually there is already a parameter above, BV, and do they have a relation? But I find all diodes have the same VR, IZ, IF and PD. Why?
