Synopsys

Inst ( model
     , name

     )

Description

Instantiation of an instance. The type of the instance is given by the model parameter. The connexions are made thanks to the connectmap parameters.

Parameters

• Model : Name of the mastercell of the instance to create (mandatory argument)
• name : Name of the instance (optional)
  When this argument is not defined, the instance has a name created by default. This argument is usefull when one wants to create a layout as well. Indeed, the placement of the instances is much easier when the conceptor has chosen himself the name f the instances.</para>
• connectmap : Connexions in order to make the netlist
  

param and map are dictionnaries as shown in the example below.

Example

Inst ( 'a2_x2'
     , map = { 'i0'  : in0
             , 'i1'  : in1
             , 'q'   : out
             , 'vdd' : vdd
             , 'vss' : vss
             }
     )

Errors

Some errors may occur :

• Error in Inst : the model Model does not exist.
Check CRL_CATA_LIB.
  Either one has made a mistake in the name of the model, either the environment variable is not correct.
• Error in Inst : port does not exist in model Model.
  One port in map is not correct.
• Error in Inst : one input net is not dimensionned.
  The size of the output nets is automatically calculated bus the input nets must be dimensionned before being connected.
