.c1.Using CBLD 3
CBLD permits the maintaining and personalizing of CUPL device
libraries. It can list the contents of a library and build new
libraries from existing ones.
A CUPL device library is a file containing descriptions of one or
more PLDs. CUPL and CSIM use device libraries to determine the
characteristics of target devices. CUPL provides device libraries
to describe all the PLDs instead of supplying individual files for
each PLD. The advantage of device libraries is that they are easier
to keep track of than multiple device files and they enable quicker
program operation.
The use of device libraries also resolves compatibility problems
between the compiler and device descriptions. Each version of CUPL
and its corresponding device library is given a matching key. If a
library is used that has a different key than the CUPL compiler, an
error message is generated during compilation and the compilation is
aborted.
The library that is created when the BUILD batch file is executed,
CUPL.DL, contains descriptions for each device that is supported by
the current version of CUPL.
o .c2.RUNNING CBLD
Run CBLD with the following command line format:
cbld [-flags] [build] [library] [devices]
where
-flags is the following set of options:
-b generate library using build file.
-e list allowable extensions.
-l list long contents of library.
-m list allowable macros by pin.
-t list short contents of library.
-u use specified library for listings.
build is the name of a file to be used with the -b option flag
library is a device library name and path name to be used
with the -u option flag.
devices is one or more device names to be used with the
-t or -l options.
========================================================
Note
The square brackets
indicate optional items.
========================================================
CBLD can be typed without any flags to see the command line format
and a list of the option flags. CBLD provides two distinct
functions: listing the contents of a library (the -t and -l
options) and building a new library (the -b option). These two
functions are described in the following sections.
o .c2.LISTING THE CONTENTS OF A LIBRARY
To list the contents of a device library, use one of the following
command line formats:
cbld -t [-u library] [devices]
cbld -l [-u library] [devices]
where
library is a device library name and path name.
devices is one or more device names.
========================================
Note
The square brackets
indicate optional items.
========================================
Use the -t flag to specify the short form, which lists only the
device names and the revision number of the library. Use the -l
flag to specify the long form, which lists the revision number of
the library and the names of the devices, and provides the revision
number, the number of pins, the number of fuses, and the number of
product terms for each device.
By default, CBLD lists the entire contents of the library; however,
certain devices can be specified to be listed. For example, by
typing:
cbld -l p16h8 p16l8 p16hd8 p16ld8 [Enter]
CBLD lists the characteristics of the p16h8, p16l8, p16hd8 and
p16ld8 devices in the CUPL.DL library as follows:
Device Rev Pins Fuses Pterms
pl6h8 08 20 2048 64
pl6l8 08 20 2048 64
pl6hd8 06 20 2048 64
pl6ld8 06 20 2048 64
Use the -u flag and a library name with either
the -l or -t flag to list the contents of a library other than the
default library specified in the environment file. For example, to
see the contents of a library named small.dl, type:
cbld -l -u small.dl [Enter]
o .c2.LISTING ALLOWABLE EXTENSIONS
The -e flag allows the listing of the valid extensions for
devices. For example:
cbld -e p22v10
The screen will display:
Device Extension
p22v10 OE D AR SP
This shows that the valid extensions for the P22V10 are:
OE output enable control
D D-type register
AR asynchronous reset
SP synchronous reset
If more than one device type must be listed, specify multiple device
names. For example:
cbld -e p22v10 ep600
The screen will display:
Device Extensions
ep600 OE D T AR CK IO DFB TFB
p22v10 OE D AR SP
If a particular device is not specified, CBLD will, by default, list
all the devices of the library.
o .c2.BUILDING DEVICE LIBRARIES
To build a new library from an existing library, first create an
ASCII build file (filename.BLD) that specifies the name of the new
library, the name of the source library, and the devices to use from
it. Any text editor can be used, once it can produce a standard
ASCII Text file.
========================================================
Note
The vertical line ( | ) separates items in the syntax that are
mutually exclusive. Do not type it in.
========================================================
The build file uses the following syntax:
TARGET
library
SOURCE
library1
devices | *
SOURCE
library2
devices | *
.
.
.
where
TARGET is a keyword to identify the new library.
SOURCE is a keyword to identify the source libraries.
library is a target library name.
library1 and library2 are source library names.
devices are device names contained in the source libraries.
* is a "wildcard" representing all devices in the specified
library.
When building a new library, devices from more than one source
library can be specified by using more than one SOURCE keyword.
Comments may be used in the build file. Enclose comments between
the /* and */ symbols. To compile the build file, use the following
command line format:
cbld -b filename.bld
========================================================
Note
There is no standard extension for build files. The .BLD extension
is for mnemonic convenience only. When running CBLD, the entire
filename, including the extension, must be typed in.
========================================================
The following example shows the contents of a build
specification file, small.bld. Small.bld specifies that a new
library, smallib.dl, be built containing the devices p22v10, f105,
and p16rp8 from the cupl.dl library, and all the devices in the
biglib.dl
TARGET smallib.dl
SOURCE cupl.dl
p22v10
f105
p16rp8
SOURCE biglib.dl
*
To run CBLD and build the smallib.dl library specified in the sample
file above, type:
cbld -b small.bld [Enter]
