обычно вялая дискуссия на форуме официальных пользователей с выходом релиза 2007 разгорелась прямо таки на повышенных тонах. Вплоть до развода и девичей фамилии. И даже крамольная мысль о переходе на Альтиум, который в последних релизах типа весьма неплох.
http://forums.mugweb.org/postlist.php?Cat=...rd=ExpeditionREto fill - а что там за бодяга в 2007.3 с шифрованием ascii, - это отдельная лицензия? Или просто лишние телодвижения? Проясните please, в чем там суть?
кстати, они не спешать бечь на 2007 - 63% мудрых осталось на 2005. Правда выборка небольшая..
Using Encrypted ASCII in Your Flow
The EE2007.3 & BSXE2007.3 releases include enhanced Automation capabilities that give you a powerful and robust method for manipulating design and library data in your flow without the data-integrity issues inherent to ASCII file manipulation.
Although Automation is superior to ASCII for modifying data securely, we understand that it will take time to update your flow to include Automation scripts. Additionally, we understand that some Automation scripts utilize ASCII data. Therefore, we will continue to support ASCII manipulation for the foreseeable future.
To protect our mutual intellectual property while enabling you to continue to use existing ASCII-based processes with minimal impact, we have added encryption to the exported library and design data in the 2007.3 releases. All imported data must also be encrypted. Therefore, if your design process utilizes the export, manipulation, and import of ASCII data, you will need to update your process.
A licensed, data-conversion module is included with the EE and BSXE 2007.3 releases. This module will allow you to decrypt the exported data and see it in native HKP ASCII format. You can manipulate the HKP data as you have done in the past but you must re-encrypt the data, using the same data-conversion module, before you import it back into your flow.
In other words, a decryption and encryption step will need to be added to the process as follows:
1. Export encrypted data.
2. Decrypt data with the supplied DataConvert.exe software.
3. Modify HKP ASCII output from the DataConvert.exe software as done in previous releases.
4. Re-encrypt modified HKP ASCII data with the supplied DataConvert.exe software.
5. Import encrypted data.If you have embedded ASCII manipulation into existing scripts, those scripts will also need to be updated. Depending on how your existing scripts or processes have been defined, you may need to add the encryption and decryption steps to the scripts themselves. Alternatively, you may be able to simply export design or library data and decrypt it before starting your existing scripts. Once the existing scripts or processes have completed, you can encrypt all the modified data and re-import it in one step.
The encryption capabilities found in the EE and BSXE 2007.3 releases contain two components: 1) the encryption / decryption software (DataConvert.exe), and 2) the license needed to run it.
The DataConvert.exe software is delivered with the EE and BSXE 2007.3 software. It can be found in the SDD_Home/common/win32/bin directory. This single module performs decryption or encryption, depending on the arguments used to run it. Directions for using the DataConvert software are found at the end of this document.
The license needed to run DataConvert.exe is available at no cost, but, to add it to your license file, you must request a copy. The part number and name for this no-cost option is 237618 - PCB Data Converter Op SW. Only one license is needed, no matter how many people at your company use it. Please contact your sales representative to request a copy.
Once the license has been added to your account, you can easily download the license file from SupportNet.
The impact to your work flow should be minimal once the new process is implemented, but we apologize for any inconvenience the new encryption methodology causes.
If you have questions concerning encryption in either the EE2007.3 or BSXE2007.3 release, please contact Mentor Support or log a service request through SupportNet.
Directions for Running DataConvert.exe
The usage for DataConvert is as follows:
DataConvert [-h] [-w] [-decrypt | -encrypt] –i <input filename> [-o <output filename>]
Options
-h Lists the command line options
-w Overwrites the specified output file (if it already exists)
-decrypt Decrypts the output
-encrypt Encrypts the output
-i Full path to the input file for the conversion
-o Full path to the output file of the conversion
The only required argument for DataConvert is to specify the input file. For example, you could use “DataConvert –i Cell.hkp”. If you only specify an input file, then the software will recognize the format of the file and convert that file to the opposite format.
If, for example, Cell.hkp was an encrypted file in the previous example, then when DataConvert finished, the same file (Cell.hkp) would be decrypted and would be in ASCII format. Running the command again on Cell.hkp would convert it back to an encrypted file.
Note: The encrypted files automatically have the .hkp file extension just like before. Using this file extension makes it very easy and convenient to encrypt and decrypt files quickly with minimal options. If for some reason you would like to create your encrypted or decrypted files with a different file extension simply specify the desired file extension in the new output file name
