Spartan and Spartan-XL Families Field Programmable Gate Arrays
DS060 (v1.6) September 19, 2001
Product Specification
1-800-255-7778
R
The four Primary Global buffers offer the shortest delay and
negligible skew. Four Secondary Global buffers have
slightly longer delay and slightly more skew due to poten-
tially heavier loading, but offer greater flexibility when used
to drive non-clock CLB inputs. The eight Global Low-Skew
buffers in the Spartan-XL devices combine short delay, neg-
ligible skew, and flexibility.
The Primary Global buffers must be driven by the semi-ded-
icated pads (PGCK1-4). The Secondary Global buffers can
be sourced by either semi-dedicated pads (SGCK1-4) or
internal nets. Each corner of the device has one Primary
buffer and one Secondary buffer. The Spartan-XL family
has eight global low-skew buffers, two in each corner. All
can be sourced by either semi-dedicated pads (GCK1-8) or
internal nets.
Using the library symbol called BUFG results in the software
choosing the appropriate clock buffer, based on the timing
requirements of the design. A global buffer should be spec-
ified for all timing-sensitive global signal distribution. To use
a global buffer, place a BUFGP (primary buffer), BUFGS
(secondary buffer), BUFGLS (Spartan-XL global low-skew
buffer), or BUFG (any buffer type) element in a schematic or
in HDL code.
Advanced Features Description
Distributed RAM
Optional modes for each CLB allow the function generators
(F-LUT and G-LUT) to be used as Random Access Memory
(RAM).
Read and write operations are significantly faster for this
on-chip RAM than for off-chip implementations. This speed
advantage is due to the relatively short signal propagation
delays within the FPGA.
Memory Configuration Overview
There are two available memory configuration modes: sin-
gle-port RAM and dual-port RAM. For both these modes,
write operations are synchronous (edge-triggered), while
read operations are asynchronous. In the single-port mode,
a single CLB can be configured as either a 16 x 1, (16 x 1)
x 2, or 32 x 1 RAM array. In the dual-port mode, a single
CLB can be configured only as one 16 x 1 RAM array. The
different CLB memory configurations are summarized in
Table 8. Any of these possibilities can be individually pro-
grammed into a Spartan/XL CLB.
