Virtutech Simics
Hello,
Have anyone tried Virtutech Simics? (hxxp://www.virtutech.com/products/simics.html) It doesn't have download area to see it Is this another VirtualPC, VMware-like software? or it's a completely new technology? It would be nice if someone could provide with a trial link for this software or any place where it can be tested. Regards. |

Hi,
I think the difference is that you have more controll on the VM Hardware, but they offer some whitepapers and i think they will awnser your question. http://www.virtutech.com/technology/whitepapers.html |

Thanks Cobi.
Well, it looks quite a powerful tool. It also allows debugging and load symbols for debugging, interesting.... Regards. |

If you're ultra paranoid and don't want to register, try:
fxp://ftp.simics.net/pub/simics/ It appears that everything is there, but I only gave it a cursory look. |

I was thrown off by that too, at first. But if you look in the "latest" directory, you'll find the install packages:
fxp://ftp.simics.net/pub/simics/latest/ It's a weird way to organize things, but they might not intend for people to be browsing the ftp directly Edit: Oh yeah, more detailed instructions are in their readme: fxp://ftp.simics.net/pub/simics/README |

Ah, you're right. Apparently they distribute custom versions for their clients, and they're all encrypted with twofish (hxxp://twofish.org). I can't say I know anything about it, except that it's 128-bit block encryption, and supposedly fairly difficult to crack. There's a little bit of discussion on it on RCE. I didn't realize that they weren't even downloadable because the one I tried to DL worked. I guess I just got lucky. Try package 55, it seems to be working. Of course, it's 100+MB and no guarantee about breaking the twofish crypto, but you never know.

Simics is more configurable than the virtual pc's out there. In simics you can specify cache's of different sizes, different replacement policies etc. So if you are a cpu or system designer, Simics is very useful to you. It is slower than VMWare so you're just interested in running an app then virtual machines will probably be faster.
I've seen the simics pub folder before but I'm not sure if there is a way to crack twofish. I believe twofish is not susceptible to clear text attack either (i.e. if you knew the unencoded first line in the file say for eg) and I know that the tf keys are 128 bits - brute force would take forever. I would really be interested in seeing if anybody could crack it. Sailor_EDA Quote:

It looks that to get a free license they ask you for lots of details about projects at school and later they review if you deserve a free license
I'm amazed with that software that can emulate a AMD64, IA64, etc machine in your 32bits machine, that's amazing! Anyway, it's quite strange that it's a powerful software and it also offers free licenses for students and there are not leaks over the internet (at least at first glance ) It would be nice if someone that has it, can upload it to the FTP Regards. |

Hello,
I managed to run Simics with the license key. (lmgrd.exe -c xxx\xxx\Simics2.0.simics.lic) The problem is when I start creating a Dredd session (x86 machine with no OS installed) to install Windows I get the following error: "License Error: module not signed. Module 'DEC21143' not loaded. Simics Module Builder license needed to sign modules. Does anyone know if I'm doing something wrong when starting the license server? or maybe that license key does not allow to create "Dredd Sessions"? (because I can create some other Linux sessions with no problems) Thanks. Last edited by peleon; 02-02-2005 at 01:51. |
