It is not required (just that if I'm not wrong, SPARK itself was checked=
  =

with Z). Z is one the language/method in this area (some are language,  =

some others are language and methods), which are mainly : SPARK, Z, B,  =

VDM, ACSL (the latter is special, it targets C :p )

You can use SPARK without knowledge of Z, while this may be interesting =
if  =

you can (I just use to know it a few). This is part of culture. Talking =

about culture, in the domain of logic applied to computer science, you m=
ay  =

be interested into learning about Intuitionistic Logic (deals with  =

constructive proof creation, which talks well to computer science)
