EDK Modelsim Behavioral Simulation Error

[hansman]

I am trying to build and simulate an FPGA System built with
EDK 6.1.1. The system contains a PPC and an Ethernet MAC.

I have set up the simulation libraries according to the getting started with edk manual.

when compiling the behavioral simulation (do system.do) modelsim 5.7g puts following errors:

If one of you knows the answer for this behavior it would be great!

modelsim 5.7g puts following errors:

# WARNING[1]: [...]:

No default binding for component: "bgo_opb_if_ila".
(No entity named "bgo_opb_if_ila" was found)

It's only a warning. When compiling the component instantiation, ModelSim
tries to find a matching entity in the library. Ignore this.

# ** Error: [...](1): near "xlxv35eb": syntax error

Means you have done something pretty stupid: a missing semicolon,
or the wrong sort of brackets, or something goofy like that.

# WARNING[4]: [...] A space is required between a number and an

identifier.

Usually happens when you try to write a time like "10ns" instead of "10 ns".
This is a nice clear error message, surely?

# ** Error: [...]: Identifier may not end with an underscore.

Which part of that do you not understand?

# ** Error: [...]: near "@®": unterminated string

The junk characters here suggest either that your text editor is allowing
you to include accented or other non-ASCII characters, or that
you are trying to compile a binary file.

# WARNING: Non-printable characters are not allowed in extended

identifiers

Same thing. An "extended identifier" is a name enclosed in backslashes
so that it can include characters other than alphanumerics. A feature
much used by automatic VHDL-generating tools like netlisters.


Check to see that you have not somehow tried to compile something that
is not VHDL source code - some of these error messages look pretty wild.

Hi,

Thanks for the info.

the problem is that the sources are ENCRYPTED VHDL provided by Xilinx EDK. Seems that the seed for the VHDL encryption files does not correctly decrypt them.

Am only I encountering such problems? I will try different modelsim versions as next step.

greets
Hans

Hi, thanks.

The problem is that the syntax errors are resulting from files that are delivered by Xilinx in encrypted VHDL! So I have almost no means to check the source of the problem.

I wonder if only I am encountering this sort of problem. Maybe it's an setup problem of modelsim/EDK?
