the explicit (intended) MOM cap is instantiated along with the extracted parasitics notice I don't want the MOM cap to be flattened-I want it to be recognized and instantiated so as to use its pdk model). The digital blocks are represented internally by subcircuits but for the user they are simple blocks. How can I prevent these empty definitions from being included in the extracted netlists? If I edit the netlist and comment them the simulation proceeds and the results seem to make sense (i.e. Chapter 6 covers simulation of digital circuits. It's not the instance that is the problem, but the model definitions need to be provided somewhere, typically via Setup->Model Libraries in ADE. iCircuit is the easiest way to design and experiment with circuits. Previously, it was defined in line XYZ of `/path/to/pdk/model/card.scs'. The error indicates that you have an instance in the netlist which is trying to instantiate a sub circuit or model that hasn't been defined anywhere. Select Spice Subcircuit from the Model Sub-Kind list to set the Spice. (d-5) All vacancies in circuit judgeships in the Circuit of Cook County, which are not allotted to Judicial Subcircuits 1 through 15 pursuant to subsection (c). For instance, in a minimalistic cell with a MOM cap I get in the extracted netlist the following definition:Īs a result, spectre complains when trying to use the extracted netlist view in a testbench:ĮRROR (SFE-3263): "path/to/extracted/netlist/cellview/spice.spc": The subckt 'cfmom_2t_p80' is being redefined. Delete the existing SIM model in the Models section by selecting it and clicking. Hi! I am getting simulation errors when trying to use the extracted netlists produced by QRC, because they contain redundant (and empty) definitions for some components.
