    System Prerequisites

This chapter lists the hardware and software prerequisites that must be fulfilled for a successful installation of the Telelogic Tau products ORCA1, SDT and ITEX.

Hardware

This section describes the hardware requirements for Telelogic Tau 3.5.

Supported Architectures

UNIX Installation Prerequisites

Telelogic Tau 3.5 on UNIX includes binaries for several different computer architectures, examples and on-line help files. During the installation, you may choose what parts to install. The tables below show the amount of disk space the different components will require.

Binaries Disk Space

Common Telelogic Tau1

8 MB

Common SunOS 5

ITEX SunOS 5

1. Add the indicated amount of disk space for the first installed Telelogic Tau product. This space is required for the components that are common to all Telelogic Tau products.
2. Add the indicated amount of disk space for the first installed ORCA and SDT architecture. This space is required for the components that are common to all ORCA and SDT architectures
3. Add the indicated amount of disk space for the first installed ITEX architecture. This space is required for the components that are common to all ITEX architectures, which includes the ITEX example files.

Optional Components Disk Space

ORCA and SDT Example files1

12

HELP files in HTML format

151

1. These files are necessary for the examples and tutorials described in the documentation. For ITEX, the corresponding files are included in the "Common ITEX" component.

If you install ORCA and SDT for the first time on SunOS 5, add Common Telelogic Tau, Common SunOS 5, Common ORCA and SDT, and ORCA and SDT SunOS 5. That is (in MB): 8 + 40 + 5 + 68 = 121 MB.

If you add software for HP 700-800, consider Common HP 700-800 (PA-RISC) and ORCA and SDT HP 700-800 (PA-RISC): 28 + 65 = 93 MB.

Windows Installation Prerequisites

Telelogic Tau 3.5 for Windows includes binaries for two different computer architectures (Windows 95 and Windows NT), examples and on-line help files. During the installation, you may choose what parts to install. The tables below show the disk space required.

The Telelogic Tau files can be installed once on a network server for all users, or locally on each user's PC.

Binaries Disk Space

ORCA and SDT PC

73 MB

ITEX PC

Optional Components Disk Space

Example files

7 MB

HELP files in HTML format

1451

1. To limit the required disk space in local PC installations, the Help files can be installed once on a network server. They do not have to be installed locally on each PC where the Telelogic Tau binaries are installed.

Run-time Prerequisites

To run the Telelogic Tau 3.5 tools properly you need a certain amount of main memory and swap size; see Operating System.

Pointing Device

A pointing device is required in order to run Telelogic Tau.

Software

This section describes the software requirements for Telelogic Tau 3.5.

Set by Windows

1. Although the exact memory needs for a high-performance ORCA and SDT installation (meaning execution with little swap page faults) on a given PC are impossible to tell, the following memory requirements could be expected:
- 32 Mb for the Windows NT system
- 20 Mb for the SDT graphical applications + 1 kB / line of SDL-PR input to the Analyzer.
- Add approx. 30 Mb for the Borland or Microsoft C compiler environment (if C code is to be generated from the SDL system).
- Add memory requirements for other applications that you want to run in the ORCA and SDT session (Microsoft Word, Netscape, etc.)
2. To double the main memory size is a good starting point.
3. Similar to a. The Windows 95 system requires only 16 Mb, though.

UNIX Graphical Environment

On UNIX, Telelogic Tau is a X Window System application to be executed under the Motif Window Manager (Mwm).

Telelogic Tau 3.5 require the X Window System, version R5 or later. The X Window System is provided by your workstation supplier.

Recommended HTML Viewers

The Telelogic Tau 3.5 on-line help requires an HTML viewer. Telelogic Tau 3.5 supports this by a simple built-in HTML viewer. It is also possible to use Internet Explorer version 4, and any version of Netscape.

ORCA and SDT Compiler Environment

A C compiler is required for the TTCN Link, SDT Simulation and Validation features, and for Cadvanced code generation for host and target environments.

For information regarding installation, see the compiler documentation.

The libraries included in the distribution of the TTCN Link, SDT Simulation and Validation features were built using the following C compilers. You are advised to install and use the same compilers, or closely compatible ones. It may be possible to use other compilers, but this is not tested or supported by Telelogic.

Architecture/OS C Compiler

Sun SPARC SunOS 5.5.1

cc SUNWspro (ANSI-C) compiler.

gcc 2.8.1 (ANSI mode)

HP PA-RISC HP-UX 10.20

c89 (ANSI-C) compiler,

gcc 2.8.1 (ANSI mode)

PC (Win32)

bcc32 version 5.2 (Borland C++ 5.02),

cl (Microsoft Visual C++ 5.0)1

1. Libraries are tested with bcc32 version 5.3 (Borland C++ Builder 3) and cl (Microsoft Visual C++ 6.0).

ITEX Compiler Environment

An ANSI-C compiler is required for the ITEX Simulation feature and for C code generation for host and target environments. A C++ compiler is required for building ITEX Access applications (UNIX only).

For information regarding installation, see the compiler documentation.

The binaries included in the distribution of the ITEX Simulator were built using the C compilers listed below, and the ITEX Access libraries were built using the C++ compilers listed below. You are advised to install and use the same compilers, or closely compatible ones. It may be possible to use other compilers, but this is not tested or supported by Telelogic.
