Layer Data Definition (DEFAULT Foundry)

In this data item, the layer information of default foundry are stored. These data are used only for the layot generation and have therefore no effects on simulation results.

Parameters

Parameter	Discreption	Range of Usage
via_ol	Overlap for inter metal via	³ 0
cond_os	Oversize of metal layer 1 (cond)	³ 0
cond_wm	minimum width of metal layer 1 (cond)	³ 0
cond_sm	minimum slot of metal layer 1 (cond )	³ 0
cond2_os	Oversize of metal layer 2 (cond2)	³ 0
cond2_wm	minimum width of metal layer 2 (cond2)	³ 0
cond2_sm	minimum slot of metal layer 2 (cond2)	³ 0
resi_os	Oversize of resi-layer	³ 0
diel_os	Oversize of dielectric layer 1	³ 0
diel2_os	Oversize of dielectric layer 2	³ 0

Notes

If only the DEFAULT foundry is available(standard packet of COPLAN), the only name for C_LAYER allowed is "C_LAYER_DEFAULT". Use of another name causes the simulator to abort!
via_ol is the minimum length of overlapping area for the connection of metal level 1 with metal level 2.
cond_os,cond2_os, diel_os, diel2_os and resi_os are used for the generation of an oversized layout ifn the corespounding layer.
cond_wm and cond2_wm can be used for definition of minimum conductor size in metal level 1 and metal level 2 respectively.
cond_sm and cond2_sm are used for definition of minimum conductor size in metal level 1 and metal level 2 respectively.
