PALASM4 Ver 1.5 is now available as freeware.

***** Technical Support Note *****

Since the PALASM software is now freeware, AMD is no longer actively
providing technical support for this product.

PALASM4 Ver 1.5 supports the PALs and the following MACH devices:

     - MACH110
     - MACH120
     - MACH130

     - MACH215

     - MACH210
     - MACH220
     - MACH230

This version contains an updated FITR.EXE Ver 1.70 which corrects
internal errors that occur when generating some MACH215 JEDEC maps.
If you already have PALASM4 Ver 1.5 installed, then read the
description for the file PATCH2.ZIP which will tell you how to update
your existing installation with the Ver 1.70 fitter instead of
reinstalling everything.

There are 6 ZIP archives and 1 PDF file:

     PALDISK1.ZIP = Contains ZIP file for PALASM4 Ver 1.5 disk 1
     PALDISK2.ZIP = Contains ZIP file for PALASM4 disk2
     PALDISK3.ZIP = Contains ZIP file for PALASM4 disk3
     PALDISK4.ZIP = Contains ZIP file for PALASM4 disk4
     PALDISK5.ZIP = Contains ZIP file for disk5
                    (PALASM/OrCAD SDT 3.21 interface)
     PATCH1.ZIP   = Fix for disassembling PALASM-generated JEDEC
                    maps.  If you have problems with disassembling
                    PALASM-generated JEDEC maps, then replace the
                    JEDMCH.EXE program that was installed with PALASM
                    with the JEDMCH.EXE, JEDMCH.MSG, and JEDMCH.PDF
                    files in PATCH1.ZIP.  Put these files in the
                    C:\PALASM\EXE subdirectory.
     PATCH2.ZIP   = Fix for the MACH215.  Some MACH215 designs will
                    cause the PALASM4 Ver 1.5 fitter to generate an
                    internal error when generating the JEDEC map.
                    This is corrected in PALASM FITR Ver 1.70 in the
                    file PATCH2.ZIP.  This zipped file contains
                    FITR.EXE, FITR.OVL, and FITR.LIB.  Put these files
                    in the C:\PALASM\EXE subdirectory.
     MANUAL.PDF   = MACHXL 2.1 documentation in PDF format.
                    Can be used with PALASM4 Ver 1.5 to learn PDS syntax.
                    Use Adobe Acrobat to read.

Download each of the 5 PALDISK# ZIP files to your PC and follow the
instructions below to create the 5 PALASM master disks. Use
PKUNZIP Ver 2.04g or later to unzip any files as described below.

Installation Instructions:

1. Create a temporary directory on your PC disk by using
   the MKDIR command:

     C:\> MKDIR pal_dir
     C:\> cd pal_dir
     C:\PAL_DIR>

2. Create five subdirectories called DISK1, DISK2, DISK3, DISK4,
   and DISK5.

      C:\PAL_DIR> MKDIR disk1
      C:\PAL_DIR> MKDIR disk2
      C:\PAL_DIR> MKDIR disk3
      C:\PAL_DIR> MKDIR disk4
      C:\PAL_DIR> MKDIR disk5

3. Unzip PALDISK1.ZIP into the DISK1 subdirectory. Unzip the other
   ZIP files into their corresponding subdirectories. Do not include
   the PALDISKx.ZIP files in these subdirectories.

4. Get 5 high-density 3.5" disks. Copy all the files in subdirectory
   DISK1 to one disk, DISK2 to a second disk, and so on.

      C:\PAL_DIR\DISK1> xcopy *.* a:
      C:\PAL_DIR\DISK1> cd ..\disk2
      C:\PAL_DIR\DISK2> xcopy *.* a:
      C:\PAL_DIR\DISK2> cd ..\disk3
      C:\PAL_DIR\DISK3> xcopy *.* a:
      C:\PAL_DIR\DISK3> cd ..\disk4
      C:\PAL_DIR\DISK4> xcopy *.* a:
      C:\PAL_DIR\DISK4> cd ..\disk5
      C:\PAL_DIR\DISK5> xcopy *.* a:

You now have a set of PALASM4 Ver 1.5 master diskettes. To install
the software, put disk 1 into your A drive and then type INSTALL.

***** NOTE ABOUT THE TEXT EDITOR *****

You will need to provide your own DOS editor.  If you do not provide
your own DOS editor and you try to edit a file, you will get the
following error message:

     STATUS:  Cannot open file:  C:\PALASM\EXE\ED.EXE

To configure the software to recoginize your own DOS editor, you can
go into the PALASM menuing system under

     FILE
          Setup...
               Working environment
                    Editor program:

and type in the path to and the name of your editor executable.

***** Bugs Notices *****

Bug   1 : Under certain conditions, the fitter will incorrectly invert
          an input register when used in a T-type equation.

      Ex: If you have the following T-type equation

             NODE ? in_reg  registered
             PIN  ? in_pin
             PIN  ? clkpin
             PIN  ? outsig  registered
             PIN  ? load
             PIN  ? read

             EQUATION
             in_reg.clkf = clkpin;
             in_reg := in_pin;

             outsig.t = load *  in_reg +
                        read *  in_pin;

          and IN_REG is an input register, then the fitter will fit
          the design, but when you disassemble the JEDEC map, you
          will get the following:

             NODE ? in_reg  registered
             PIN  ? in_pin  pair in_reg
             PIN  ? clkpin
             PIN  ? outsig  registered
             PIN  ? load
             PIN  ? read

             EQUATION
             in_reg.clkf = clkpin;
             in_reg := in_pin;

             outsig.t = load * /in_reg +
                        read *  in_pin;

     IN_REG has been incorrectly inverted in the OUTSIG equation.

Work-around: Set "Automatic pin/node pairing" to 'N' in the Logic
             Synthesis options menu, and do any input or output
             pairing manually. For the example listed above, manual
             pairing is done in the pin/node declaration section.

             NODE ? in_reg  registered
             PIN  ? in_pin  pair in_reg
