Layer Data Definition (Default Foundry) C_LAYER

Symbol :

Parameters :

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

Notes/Equations/References :

  1. 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.
  2. If only the DEFAULT foundry is available (standard packet of COPLAN for ADS), the only name for C_LAYER allowed is "C_LAYER_DEFAULT". Use of another name causes the simulator to abort!
  3. via_ol is the minimum length of overlapping area for the connection of metal level 1 with metal level 2.
  4. cond_os and cond2_os as well as diel_os and diel2_os are used for the generation of an oversized layout.

  5. cond_wm and cond2_wm can be used for definition of minimum conductor size in metal level 1 and metal level 2 respectively.
  6. cond_sm and cond2_sm can be used for definition of minimum slot size in metal level 1 and metal level 2 respectively
  7. Following values could lead to an incorrect layout generation :
      8. via_ol > cap_l (see C_TECH)
      via_ol > res_l (see C_TECH)
      cond_wm < 2*|cond_os| if cond_os<0
      cond_sm < 2*cond_os if cond_os>0
      cond_wm < 2*|cond_os| if cond_os<0
      cond2_sm < 2*cond2_os if cond_os>0
