6. Select Setup - Model Libraries, and specify the path to the converted text.
7. Set the model property on the block to be the same as the top-level subcircuit name in the converted
text. You might also need to add the model property. To specify the model property,
• Select the block
• Select Edit - Properties - Objects.
• Click Add in the User Property section.
• Specify the name as model, and type as string. You can leave the other two fields blank.
• In the Edit Object Properties form, specify the name of the top-level subcircuit against Local
Value and click OK.
What you have in the netlist is an instance statement for the block representing the converted netlist that
looks something like this:
¤
And a converted netlist that has a top-level subcircuit name that corresponds to this.
Note: Using a version older than 4.4.3, might be complicated because of name mapping/ subcircuit unfolding
issues.
Procedure 2:
1. Create a schematic and add the pins required.
2. Create a symbol from the schematic to automatically add the CDF parameters. Alternatively, you can
open the schematic and then select Design - Create Cellview - >From Pinlist....
3. Check if the terminal list provided in the CDF is correct and in the right order. You can do this using
(CIW) Tools - CDF - Edit... and enter the library/cellname in the form.
4. In the CDF form, change the CDF Type from Effective to Base. This will save the changes to disk.
5. Select Simulation Information and click Edit.
6. In the Edit Simulation Information form, choose spectre.
7. In the new form, you will find componentName=subcircuit. Change subcircuit to the exact name of
your subcircuit netlist. Your spice netlist must be a subcircuit. Then OK both forms.
8. In the Library Manager, copy the symbol to a view called spectre. This is very important.
9. Put the symbol in the schematic you want.
10. In Artist, select Setup - Environment... The Environment Options form comes up.
11. Select Y against Use SPICE Netlist Reader(spp). This ensures your spice subcircuit will be translated
to Spectre during simulation.
Note: Make sure your subcircuit file is added to the model library.
