Supports all analog languages

Imports files written in Spice, HSpice, PSpice, Spectre, DSPF, and CDL languages.

Yes

Yes

Supports all digital languages

Imports files written in Verilog, SystemVerilog, and VHDL languages.

Yes

Yes

Supports all mixed-signal languages

Imports files written in VerilogAMS and VHDLAMS languages.

Yes

Yes

Eliminates dependency on the deprecated DPL mechanism (Better performance)

DPL is an intermediate representation of a parsed netlist file which is a SKILL list of lists, but it is outdated. The recommended mechanism is using VPI to read data directly from the parsed file.

No

Yes

Eliminates dependency on the deprecated -use5x command line option (Better performance)

The -use5x option is not scalable and is outdated. It is only available from the parser to generate the library, cell, and view structure.

No

Yes

Integrates library definitions through cds.lib

Eliminates the need to specify reference libraries and their paths manually in the parameter file.

Yes

Yes

Connectivity information in the shadow database in case of implicit connections

Mandates the shadow database to have the following connectivity information, if the instance line in the netlist file has implicit connectivity.

• Implicit connectivity. For example, resistor R0 (a,b).
• Explicit connectivity. For example, resistor R0(.PLUS(a), .MINUS(b)).

Yes

Yes

Blackbox support

Allows importing only the top level interface information of a cell that might contain millions of instances. The interface information is imported without processing the instances.

No

Yes

Creation of symbolic link to netlist file

Creates a symbolic link to file in the library/cell/view structure without importing the actual netlist file

No

Yes
