CROSS COVERAGE

In reply to dave_59:

Thanks a lot Dave,
May i know the difference between crossing coverpoint lables and crossing variables?
For example
1.cross c_sif_load, c_bypass, c_b, c_mem, c_m, c_sif_reg; (222322) bins ?
2. cross sif_load, bypass, b, mem, mode, sif_reg; (2
22321632) bins ?

1.If we mention coverpoint or coverpoint label in cross will it take only explicit bins created in that coverpoint for cross coverage automatic bins?
2. if we mention variable in cross will it take all possible combinations during cross coverage automatic bins?
