The GDF File
The GDF file is a simple text description of the design
function, device and pin parameters. The file has four
parts: device selection, set and constant statements, a
pin section and a connection section. A sample file looks
like this:
// 32-Bit Data 3 to 1 Mux

PARAM SECURITY ON;
PARAM OPENDRAIN ON;

BUS_D.s0 = sel0;
BUS_D.oe = oe;
BUS_D.clk = clk;
END
This example shows a simple, but complete, 32-bit 3:1
MUX design. Once completed, the compiler takes over.
Powerful Syntax
Lattice
’
s ispGDX Design System uses simple, but power-
ful, syntax to easily define a design. The !(bang) operator
controls pin polarity and can be used in both the pin and
connection sections of the design definition. Dot exten-
sions define data inputs, select controls for the 4:1
multiplexor, and control inputs of sequential elements
and tri-state buffers. Dot extensions are .M# (MUX Input),
.S# (MUX Select), and control functions, such as .CLK,
.EN, .OE and .A (shown in adjacent table). Pin Attributes
are assigned in the pin section of the GDF as well.
SLOWSLEW selects the slow slew rate for an output
buffer. The Pull parameter can be used to select the
internal pull-up or bus hold latch. OPEN drain can be
used to select open drain operation. The COMB attribute
distinguishes the structure for bidirectional pins. If COMB
is used, the input register, or latch, of an output buffer will
be applied to bidirectional pins.
Please consult the ispGDX Development System Manual
for full details.
