Modeslsim VHDL library distributionThis is a discussion on Modeslsim VHDL library distribution within the vhdl forums in Programming Languages category; Hi All, Does anybody know the best way of distributing modelsim libraries, keeping the VHDL source code private? Obviously I can distribute a precompiled library, compiled with the - nodebug switch, but AFAIK the library format can and does change between Modelsim releases. This means I will need to distribute a precompiled library for every release i want to support, on each platform. The other alternative i thought of was to write a program that has the source code embedded (in encrypted format) and invokes vcom at the command line. The problem with this is that the source will need ... | ||||||||

The other alternative i thought of was to write a program that has the source code embedded (in encrypted format) and invokes vcom at the command line. The problem with this is that the source will need to be written to a file in the clear for vcom to operate on. Any help would be appreciated. Cheers Rob  |

Newer version of Modelsim can always update the older database version, but of course not the other way. The commands are "vcom -refresh" and "vlog -refresh". And the compiled format is platform independent if the platforms have same amount of bits (32/64b difference). > The other alternative i thought of was to write a program that has the > source code embedded (in encrypted format) and invokes vcom at the > command line.

With verilog code there would be more options for native code encryption in recent Modelsim versions. --Kim |
