clex18.in : GDS2, netlist reduction and contact statement

Requires: CLEVER

We show in this example that CLEVER can be used with a gds2 layout format as input. The commands used are GDS2="layout.gds" and cell="cell_number1" which allow the user to load a gds2file and select a specific cell in the layout.

Netlist reduction for capacitance and resistance extraction are also available in CLEVER. Since we perform the capacitance and resistance extraction with one Interconnect command, we need to define two different minvalues. Therefore the keywords minRES and minCAP have to be set in the Interconnect command like:

Interconnect minRES = 0.001 minCAP=1.0e-18.

Finally we show in this example that the Interconnect statement was extended by the option Contact = <string>. This allows the user to specify one particular conductor for which CLEVER extracts the capacitance values with respect to all other conductors. If more than one interconnect statements are invoked during the course of the simulation, the last results of capacitance calculation will replace the previously calculated values that already exist in the netlist.
