Autocode with UCB in Fortran

[peteanif]

Hi,

I use a schema for modeling a system and I use some UCB blocks inside. The source codes are written in C and Fortran languages. In Xmath environment there are no problerms: I can do the simulation; Matrixx compiles and links all the codes.

I have a problem when I make the autocode: I do this by autocode tool in the block browser, and the code generated is in C.

All the name of the Fortran procedures are written in lower case but the Fortran wants the procedures's names in higher case (it is case sensitive) so there is an error when these procedures are called.

Also, the TIME parameter is passed by value and not by address: I have to put the '&' before the parameter. I use the C compiler with '_stdcall' mode for parameters pass
ing.

I don't use a particular template to make the autocode: I use the standard function in the graphic tool.

If there is a way to do this automatically, please tell me.

Thanks,
Francesco

When using a UCB in SystemBuild both a Fortran template (usr01.f) and a C template (usr01.c) are available in the SystemBuild\src directory. To use a UCB in SystemBuild and in AutoCode a different UCB template is needed. This is the sa_user.c file in case\acc\src. There is no template for Fortran so I would recommend creating a wrapper c file based on the UCB template that in turn calls your Fortran code.

Ok, I used the usr01.f template for the SystemBuild simulations and I created a .dll with the Fortran Compiler and linked this .dll to the autocode.

I'll try to use a UCB in C, that calls the Fortran routines.

Thanks,
