Help about netlist translation

[gnomix]

Hi to all,
someone know how I can perform a retargetting from an edif netlist (xilinx) to an other technolgy?
My problem is about the netlist format:
************************************************
(instance BU182
(viewRef view_1 (cellRef LUT4 (libraryRef xilinxun)))
(property HU_SET (string "my_design/c1/cm_top"))
(property RLOC (string "x1y4"))
(property INIT (string "6969"))
*************************************************
If I read this netlist into synopsys design compiler I have a lots of black-box because the function of the LUT are lost.

Thk in advance

You need specified the synthesis library to xilinxun library.

Hi PatrickChen,
thanks for your kindly answer.
I have already set the link library to the xilinx libs, instead I have set the target library to the new technology.
When I perfort the translate I'm receiving a lots of this warning:

Warning: Cell 'BU172' (XORCY) not translated. (TRANS-1)

and when I perform the report_cell I see:


Cell Reference Library Area Attributes
--------------------------------------------------------------------------------
BU155 dfnpn cx2001_core 2.00 n <---- translated cell (only FF)
BU162 LUT4 xdc_virtex2-5 1.00 b, d
BU165 MUXCY xdc_virtex2-5 0.00 d
BU166 XORCY xdc_virtex2-5 0.00 d
