Synopsys: Where can I get a list of all components I am able to instantiate? How can I get a listing of all library cell names in a XSI Library?
Description
Key Words: instantiate, library, XSI, primitives
Urgency: Standard
Description: Virtually any Xilinx primitive may be explicitly instantiated into a VHDL or Verilog design if the component name and the associated pin names are known. This solution describes where this information is documented for M1 and XACT 5.2.1. This solution record also states the procedure for listing the library cell names of a Xilinx Synopsys Interface (XSI) library (.db file).
If you need further assistance with how to instantiate these primitives, please refer to the documentation listed below.

M1 documentation ================
FPGAs:
A complete list of all primitives which may be instantied for FPGAs is located in the Dynatext on-line documentation in the M1 manual "Synopsys (XSI) Interface/Tutorial Guide", Appendix A.
A quick reference of commonly instantiated components is located in Appendix G of the "M1.3 Alliance Series Quick Start Guide."
CPLDs:
A list of components which may be instantiated and/or inferred for the CPLD families (XC7000 and XC9500) may be found in Appendix A of the "CPLD Synthesis Design Guide" also located in the Dynatext on-line documentation.
All Devices:
For information on the function of each of these primities, please refer to the M1 manual entitled "Libraries Guide" in the Dynatext on-line documentation.

Using Synopsys to find out library cells ========================================
If you do not have access to the fore mentioned manuals, you can obtain a listing of the library cells by using Synopsys commands.
(1) Start dc_shell or the design_analyzer in a directory which contains your .synopsys_dc.setup file. The .synopsys_dc.setup file should already be pointing to the libraries you need for synthesizing a design in the XSI flow.
(2) In the command window of design_analyzer, or in dc_shell, type the following and the hit the enter key:
read -f db link_library
(3) Next, type in the command window of design_analyzer, or in dc_shell, type the following and hit the enter key:
list -files
This will list all the library files in memory.
(4) For each item on the list, type the following in the command window, or dc_shell:
find cell filename/*
where filename is the string in front of the .db extentions.
For example, lets say that list -files gave you the following:
Synopsys always list cell names with the name of the .db file which contains the cell. The actual cell name is the name after the '/'.
(5) Note, some cells, even though you can get a listing on them, should never be instantiated by the user, like the clb_4000 or iob_4000 cells, which are FPGA Compiler primitives used by the synthesizer only.
