PHP Perl Substition with multiple conditions

I have a text file that contains lines similar to the following:

-----------------------------------------------------------
fall for setup

CSHRC0 'gnd';
CSHR0 'gnd';

rise for setup

rise for hold

CSHRC0 'gnd';
CSHR0 'gnd';

fall for hold
------------------------------------------------------------

I am trying to replace the gnd in between fall for setup and rise for setup with 0.75*vdd.

I tried the following:
Code:
perl -e 's/gnd/0\.75\*vdd/ if m/CSHRC0/ && /fall\ for\ setup/ .. /rise\ for\ setup/' -pi file
perl -e 's/gnd/0\.75\*vdd/ if m/CSHR0/ && /fall\ for\ setup/ .. /rise\ for\ setup/' -pi file

But these don't seem to work at all. I believe the problem is with how I am using the && operator to combine both conditions, since if I use any of those two conditions separately they would work. How can I apply multiple if conditions to the same substitution?
