What Altera Support

Altera Max+Plus II support 3rd Party EDA tools through EDIF

EDIF is a standard file transfer format between different EDA tools

Altera Max+Plus II

Synopsys

Cadence

Mentor Graphic

EDIFEDIF


Is it so simple ?!?!

Is it true that EDIF can handle all the different EDA tools conversion

Answer is Yes and No Yes -- bascially all the EDA tools can accept EDIF file

and understand it No -- EDA only provide major information to the EDA

tools, except the EDIF file, we also need to provide a file name as “LMF” -- LLibrary MMapping FFile


What is LMF -- Library Mapping File

LMF is a kind of – pin to pin mapping

– gate to gate mapping

– Power and Ground signal mapping

Pin to Pin Mapping– A->1, B->2, C->3

Gate to Gate Mapping– AND2 -> 2AND

Power and Ground signal Mapping– Vcc -> Vdd

– Gnd -> Dgnd

Two Input AND gate

Example of LMF% 1-bit full adder %BEGINFUNCTION 7482 (A2,A1,B2,B1,C0)RETURNS (SUM2,SUM1, C2)FUNCTION "ad01d1" ("GND", "a", "GND", "b", "ci")RETURNS ("", "s", "co")END

% 2-bit full adder %BEGINFUNCTION 7482 (A2,A1,B2,B1,C0)RETURNS (SUM2, SUM1, C2)FUNCTION "ad02d1" ("a1", "a0", "b1", "b0", "ci")RETURNS ("s1", "s0", "co")END

Who provides the LMF

Altera will provide LMF for some commonly use EDA tools– Cadence– Exemplar– Mentor Graphics– Synopsys– Synplicity– Viewlogic

But some minority EDA tools need to provide by – EDA vendor– create by the customer itself


Example : Synopsys interface with Altera


Design Interface


Processing Interface


Simulation Interface


Step 1 -- Read in the Synopsys EDIF


Step 2 -- Open the Compiler Window

Click the “Interface” Option


Step 3 -- Select the LMF

Select the EDA vendor’s LMF


Step 4 -- that it, you can compile the design


If I want to provide custom make LMF

Select the LMF as you want


Max+Plus II can IN/OUT

Max+Plus II take the EDIF file

Max+Plus II can output EDIF file

Max+Plus II can output Verilog HDL file

Max+Plus II can output VHDL file


Conclusion

Altera Max+Plus II interface the other EDA tools with – EDIF

– LMF

You can also output EDIF from Max+Plus II to other EDA tools– but Altera does not provide the corresponding LMF file

But you can output VHDL or Verilog file instead of EDIF file
