Crypted file is corrupted or key is outdated

Jump to solution

Hi,

 

I am trying to simulate the LVDS receiver of Virtex6.

 

I am using eldo with the hspice compatibility option on.

 

When running eldo I get the error 'Crypted file is corrupted or key is outdated'. I just downloaded the model 'mbx40-r0.22.lib'.

 

Is there any other thing I need to do than including the file with a .include instruction?

 

Is there any information from Xilinx how to use encrypted files (I could not find any)?

 

Thanks.

g,


We have had that request before, but there have been so few of them, that it was never justified to spend the money, to provide the models in that format.  Hspice is the 'golden standard' so it makes sensee for us to support it.  All of the others (some of which we use as well), always boils down to "how does it compare with hspice?"


As the models of the devices belong to the foundry, we are not allowed to distribute the spice files unencrypted.

 

If you ask for a Xilinx IO FAE specialist, they can run the simulation for you if this is holding up you getting your board designed (and us getting orders for parts).

 

The IBIS files are extracted from our spice results (spice2ibis), so the IBIS files should be adequate for 99% of the tasks.  I'd like to know what INIS is unable to model for you, if for some reason you cannot use IBIS.

 

The spicie transistor models reflect the devices fabricated by the foundry (all of our models are continously monitored, and updated if necessary -- the foundry modifies the process to stay inside the models).

g,

 

The encrypted spice files are for HSPICE (tm, Synopsys).

Perhaps you need to ask your vendor if they support HSPICE encryption, also?

Thanks for the reply.

 

Eldo can read hspice netlists, so I assumed it could also read encrypted netlists. I will ask my vendor about encrypted files specifically.

Hi Austin,

 

We got the confirmation from our vendor that eldo cannot read encrypted hspice netlists.

 

Also according to him, it would be easy to generate an eldo encripted netlist if the original hspice netlist were available.

 

Could Xilinx provide an eldo encripted netlist of the Virtex IO?

 

Thanks and regards.

Hi Austin,

 

thanks for your reply.

 

We will use the IBIS models.
