Components for installing SDF-SIM
The statements that can be passed to SDF-SIM are defined in the syntax file SYSSDF.SDF-SIM.046.
The following files are supplied as part of SDF-SIM:
SYSLNK.SDF-SIM.046 SYSSDF.SDF-SIM.046 | Library containing the module SDF-SIM. Syntax file containing the SDF-SIM statements and the START-SDF-SIM command. |
SYSMES.SDF-SIM.046 | SDF-SIM message file |
Coexistence between different SDF-SIM versions
The START-SDF-SIM command (see "Working with SDF-SIM") invokes the SDF-SIM version that was specified for the user ́s system by the system administrator. This will usually be the latest SDF-SIM version. It is, however, also possible to call an older SDF-SIM version if desired. The following steps are required for this purpose:
- Create a user syntax file with SDF-A and copy all SDF-SIM statements of the desired SDF-SIM version into it (using the COPY statement). The required SDF-SIM statements can be found in the system syntax file that was supplied with the desired SDF-SIM version (SYSSDF.SDF-SIM.<version>).
- Activate the created user syntax file with the MODIFY-SDF-OPTIONS command (see the “Commands” manual [4] (Related publications)).
- Call the desired SDF-SIM version with the following command:
/START-EXE *LIB-ELEM(LIBRARY=$.SYSLNK.SDF-SIM.vvv,ELEMENT=SDF-SIM) 1
<version> is the desired version number, e.g. 041 for SDF-SIM V4.1.
or
/START-SDF-SIM VERSION=<version>
<version> is the desired version number, e.g. 041 for SDF-SIM V4.1.
1 The command used here, START-EXECUTABLE-PROGRAM, is available in BLSSERV V2.3 and higher (the command START-PROGRAM is to be used if necessary).
Starting SDF-SIM
SDF-SIM is started by means of the following command:
START-SDF-SIM Abbreviation: SDF-SIM |
VERSION = *STD / <product-version> ,MONJV = *NONE / <filename 1..54 without-gen-vers> ,CPU-LIMIT = *JOB-REST / <integer 1..32767 seconds> |
VERSION=
Allows the user to select the desired SDF-SIM version if multiple versions of SDF-SIM were installed with IMON. If the version is specified within single quotes, it may be preceded by the letter C (C-STRING syntax).
If the product was not installed using IMON or if the specified version does not exist, VERSION=*STD applies (see also “Coexistence between different SDF-SIM versions”).
VERSION=*STD
Calls the SDF-SIM version with the highest version number.
VERSION=<product-version>
Specifies the SDF-SIM version in the format m.n[a[so]] (see also “product-version” (SDF syntax description)).
MONJV =
Specifies a monitoring job variable to monitor the SDF-SIM run.
MONJV = *NONE
No monitoring job variable is used.
MONJV = <filename 1..54 without-gen-vers>
Name of the job variable to be used.
CPU-LIMIT =
Maximum CPU time in seconds which the program may consume for execution.
CPU-LIMIT = *JOB-REST
The remaining CPU time available is to be used for the job.
CPU-LIMIT = <integer 1..32767 seconds>
Only as much time as is specified is to be used.
You can then enter the statements for preparing the simulation (DEFINE-TEST-OBJECT, DEFINE-ENVIRONMENT).
The simulation is started after entry of the START-SIMULATION statement. SDF-SIM first of all displays the current syntax file hierarchy, then it displays an asterisk (*) prompting you to enter the command or statement to be simulated.
Terminating SDF-SIM
During simulation ('*' prompting), SDF-SIM can be terminated by entering the string ’/*’.During the preparations for simulation (’%//’ prompting), this can also be done with the aid of the SDF standard statement END.
Features of a simulation run
The following example shows the basic features of a simulation run.
/START-SDF-SIM | ||
|
|
|
%//START-SIMULATION | ---- Starting simulation | |
|
| ---- Commands / statements to be simulated |
*/* |
The statements for preparing simulation can also be specified more than once. In such cases, the settings made with the last statement of the same sort apply.
