Cadence Xcelium doesn't support variable substitution in if-condition about tvip-axi

hi @kazt81 ,

Thank you for your reporting this error.
I will fix it.

But I think this is valid SV code so Xcelium should accept this code.
Can you also report it to Cadence?

operator_assignment ::= variable_lvalue assignment_operator expression
assignment_operator ::=
= | += | -= | *= | /= | %= | &= | |= | ^= | <<= | >>= | <<<= | >>>=
expression ::=
primary
| unary_operator { attribute_instance } primary
| inc_or_dec_expression
| ( operator_assignment )
| ...

Can you check this fix works with Xcelium simulator?
