Modelsim vs ISE : usage of internal devices.

modelsim 6.4+compxlib

Hi All,

I'm a novice in fgpa design. I worked on small asic design and now I'm design on xilinx fpga.

I don't understand how use correctly eda tools.

I mean :

I start with the schematic editor in ISE to choose the right devices and top-level design. I'm using a DCM and a FIFO.

After this I would simulate with modelsim but I dont know how link the library.

I read that on other simulator, as Active hdl, there are precompiled library for fpga. But not for modelsim.

How I can do this ?

A more general question : How the correct way to work ? Do you start form ISE to add embedded device by Architecture Wizard ? Or from an other tool and, in this case, only component and generic for embedded device.

Someone can clarify me how do this ?

See if this helps

ise compile modelsim library

:| Thank you, but isn't my case.

I work with modelsim se and not xe. With xe no additional operation on library is needed but only init addition. This is what I read on xilinx and on the doc that you linked.

Who worl with modelsim SE ? Addional compilation is indicated on Xilinx site. But I dont known how to do it.

Please.....help me!

modelsim 6.4 ise

in modelsim 6.4 library are already compiled u have to only add these from its location...in its lower version u have to compile libraries
core gen
sim prim
unisim
in this way u can link d libraries

way 2 work on ISE navigator
after design entry compile by ISE then i check d simulation through modelsim
on top left simulation/synthesis and other option given choose from there

now synthesis ur design
then post simulation PAR then configure and then dump over fpga/cpld....this completes ur work on ISE

modelsim se and ise 11

OK!

But in modelsim library I do for "add new library" and I search a compiled library in xilinx ISE dir. But I don't find it. Where are ?

If I have understand, you design your total project in ISE ( schematic or vhdl code, testbench ) and launch modelsim ( simulator ise default ) to check your design. Is correct ?

No need to copy and paste src code. I'll try this mode. Thank you.

May you indicate me where are the compiled library ?

adding modelsim path to ise

Read about "compxlib" in xilinx.

modelsim se vs ise

Thank you.

I found it. On Ise by compxlib, I compile unisim, coregen...... library and a modelsim.ini file is created in the project dir.

And so, I added this library path in my modelsim.ini. In this way I can simultate with modelsim without launching it inside ISE.

Thank you very much.

Bye.
