Physical Verification Tools Current design rule checking (DRC) tools need to be enhanced to handle the design rules associated with inter-chip contacts. In addition, the parasitic extraction tools have to consider coupling between adjacent device layers as well as the RLC parameter of inter-chip contacts. One important concern is the electromagnetic noise in the whole system since isolation among different devices is hard to guarantee.

Table 20.4 defines typical design rule checking that is performed, the reasons for checking, and the method of checking. 

Bare-Board Analysis. Several physical artwork problems are not discovered by design rule checking and are not strictly speaking the result of design rule violations. Nonetheless, these problems can affect the manufacturabiUty of a board and its yield. Table 20.5 describes some of these issues.

Other desirable features include the ability to do three-dimensional (3-d) modeling view cross sections through the 3-d model and design rule checking (DRC) and libraries of standard MEMS components such as comb-drives, bond pads, and mechanical test structures.
