Problem Title:
A1.5: Cadence Concept 9604 and 97a: How to target a Spartan device


Problem Description:
Keywords: Concept, Spartan, Spartanxl, -family

Urgency: Standard

General Description:  Due to a limitiation in the current version
of the Cadence Concept EDIF netlister, a simple work-around is
necessary to create an implementation netlist when targeting
Spartan and SpartanXL devices with the Alliance 1.5 software.


Solution 1:


The command-line based EDIF netlister provided by Cadence,
Concept2xil, does not allow the device family spartan or
spartanxl to be selected.  To work-around this problem, it is
suggested to use the family xce4000e for Spartan devices and
xce4000x for SpartanXL devices.  To do this you must first add to
the project's cds.lib the following lines:

define xce4000e_syn <path_to_Xilinx_install>/cadence/data/spartan_syn
define xce4000x_syn <path_to_Xilinx_install>/cadence/data/spartanxl_syn

When invoking Concept2xil, use the following command-line:

For Spartan:
 concept2xil -family xce4000e <design>

For SpartanXL:
concept2xil -family xce4000x <design>

The addition of Spartan, SpartanXL and other new Xilinx families
will be made to the PE 13.x of Concept and supported in the
next release of the Xilinx software.
