[Magic-dev] scmos-tm.tech drc question

[Bertrand Irissou]

 Hi Tim,

 Looking into the scmos-tm.tech file I came across the following 
observation:

The layer "pad" is defined on the metal2 plane. It is not defined as a 
contact.
However, on line 3000 of the scmos-tm.tech :

     spacing 
pdc/m1,ndc/m1,psc/m1,nsc/m1,hpdc/m1,hndc/m1,hpsc/m1,hnsc/m1,pc/m1,ec/m1,capc/m1,clc/m1,emc/m1,pbc/m1,nbdc/m1,m1,m2c/m1,gc,pad/m1 
pdc/m1,ndc/m1,psc/m1,nsc/m1,hpdc/m1,hndc/m1,hpsc/m1,hnsc/m1,pc/m1,ec/m1,capc/m1,clc/m1,emc/m1,pbc/m1,nbdc/m1,m1,m2c/m1,gc,pad/m1 
2 touching_ok "First-level metal spacing must be at least 2 (MOSIS rule 
#7.2)"

 there are statements referring to pad/m1.

 However I have checked that pad spacing to metal1 violations are not 
reported.
 Is this the intended behavior ? If so, should magic report a problem 
during reading the technology file ?

 Thanks,

 Bertrand.
