is modelsim really necessary?



i am learning how to create a microblaze thru this tutorial  http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/edk_ctt.pdf


in the tutorial i read the following paragraph:


1. A Secure-IP capable mixed language simulator (ModelSim PE/SE v6.4b or NCSim 8.1- s009 or later) must be installed for the simulation steps. MXE is not supported for embedded designs; it doesn't have mixed language or SecureIP support. Optionally, install the CoreConnect™ toolkit. The CoreConnect toolkit is only required if you intend to perform Bus Functional Model (BFM) Simulation. If you do not intend to run BFM simulations, you may skip installation of the CoreConnect Toolkit. CoreConnect is a free utility provided by IBM. You can download CoreConnect from the Xilinx website at: http://www.xilinx.com/xlnx/xebiz/designResources/ip_product_details.jsp?key= dr_pcentral_coreconnect. After you make the appropriate selections on the web page to order and register, you will have access to the download. Simulation Installation Requirements

2. If you haven’t already done so, compile the simulation libraries following the procedure outlined in the EDK help system.

        a. To open the help from XPS, select Help > Help Topics. Alternately, the XPS Help is available on the web at                          http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/platfor m_studio/platform_studio_start.htm.

        b. Navigate to Procedures for Embedded Processor Design > Simulation > Compiling Simulation Libraries in XPS >              Compiling Simulation Libraries in XPS.


so my question is:

a.is this really necessary?

b.is modelsim part of the ise design suite 13.1

c.if a is yes and b is no where can i get modelsim?

Re: is modelsim really necessary?

a. yes b. no

Modsim is a simulation tool by the Mentor Company, not a tool from Xilinx. Xilinx also has their simulator: ISIM (in the ISE suit).

Modsim, in my experience, is more convenient and more powerful / faster.


You can get the modsim sotfware from the website of Mentor   http://www.mentor.com/products/fv/modelsim/

Re: is modelsim really necessary?

Please make sure that you are using the supported version of Modelsim with ISE13.1.
REfer to page 32 of http://japan.xilinx.com/support/documentation/sw_manuals_j/xilinx13_2/irn.pdf for supported list

Re: is modelsim really necessary?

i saw that it isnt free... is there a free simulation software and does it work on windows 8.1? why cant i use isim for the embedded simulation??? thanks
