- Trouble Shooting Problems Using OrCAD/SDT III Within PALASM 4.
- ---------------------------------------------------------------------
-
- PALASM 4 should be compatible with all versions of OrCAD/SDT III from
- version 3.21 or later. Earlier versions or the latest version 4.0 will not
- work successfully with the PALASM 4 interface programs.
-
- Before installing the MACH libraries and the PALASM 4 interface you must
- have already successfully installed the OrCAD/SDT III software. Before
- starting your PALASM 4 installation you must note the drive and directory
- where the OrCAD/SDT executables are located. You will be requested to input
- this information during the installation process.
-
- The following OrCAD programs are used by PALASM 4 to process data:
-
- 1. DRAFT.EXE ... Schematic Editor.
- 2. FASTSCAN.EXE ... Build list of all separate sheets.
- 3. CLEANUP.EXE ...
- 4. ANNOTATE.EXE ... Annotate signals across schematic.
- 5. ERC.EXE ... Schematic Error Check.
- 6. CROSSREF.EXE ... Schematic signal cross-reference list
- 7. INETLIST.EXE ... Schematic to JNL netlist translator.
-
- It should be noted that although PALASM 4 will successfully trap errors
- generated from the OrCAD software, the on-line help does not currently
- recognize them and give additional help.
-
- Errors while compiling Schematics
- ---------------------------------
-
- The most common problem with an OrCAD/PALASM 4 installation is the
- correct definition of ORCADSDT.OVL. This file is used by the OrCAD
- software to define the paramters and libraries to be used by the OrCAD
- software. When ORCADSDT.OVL is not in the local working directory the
- PALASM 4 software automatically copies it from the directory used to
- store the OrCAD executables. So keep an up-to-date copy in this
- directory. To use the OrCAD software a copy of this file must be
- located in every working directory.
- -----
-
- If there is a problem with the integration of the OrCAD and PALASM 4
- software, during the compilation, the OrCAD software will typically
- error with:
-
- MS-DOS error #2 (or #3)
-
- To fix this error you must exit the PALASM 4 menu and return to the
- DOS command prompt.
-
- **********************************************************************
- * the steps below demonstrate how to update the ORCADSDT.OVL file
- * using default directory information. You must substitute the correct
- * directory information used during your install of PALASM 4 and OrCAD/SDT.
- *********************************************************************
-
- Move to the main ORCAD executable directory:
-
- C: [enter]
- CD \ORCAD [enter] (note: default ORCAD path)
-
- Use the Orcad DRAFT utility to modify the ORCADSDT.OVL file by typing:
-
- DRAFT /C [enter]
-
- The library path should point to the PALASM 4 library subdirectory, so
- update by typing
-
- LP
- C:\PALASM\LIB\ (note: default PALASM path)
-
- Ensure the correct MACH libraries are installed, update by typing:
-
- LF
- A
- 1 [enter]
- 74XX.LIB [enter]
- A
- 1 [enter]
- LOGIC.LIB [enter]
- A
- 1 [enter]
- MACH.LIB [enter]
- Q
-
- Exit the update of ORCADSDT.OVL by typing:
-
- U
- Q
-
-
- Once you have a correct ORCADSDT.OVL make a copy to your Orcad executable
- directory for future use. Restart the PALASM 4 menu and try compiling again.
