Verify Circuit Apportionment

DESIGN PHASE:       preliminary design
SUB ELEMENT NAME:   verify circuit apportionment
VARIABLE NAME:      [HEPVCA]
DATE:               REVISION LETTER:     REVISION DATE: 
APPLICABILITY:      all circuits

ACTIVITY: Verify that the circuit apportionment of the verified
circuit concept is still valid.

OUTPUT: Validation that all circuit functions are part of the
circuit or are contained in an interfacing circuit and that the
module area and height of components above the module are equal
or less than that allotted in the base line design.

ALGORITHM:

[HEPVCA] =          engineer hours to verify circuit apportionment
0.0+                set up time
0.0*                time per part
[PARTS COUNT]       circuit parts count

DISCUSSION:

Growth beyond the allotted base line volume may affect module
count, chassis size, weight, and other critical system
parameters.  An early recheck of the circuit apportionment
minimizes risk in this area.
