The Clear Logic CL8000 Laser-Configured ASIC (LASIC
) family
offers the ultimate combination of performance, flexibility, and
cost. This family is a system level second source to Altera
FLEX
8000 products. For designs not requiring in-system
reprogrammability, design verification can be performed using
the programmable Altera devices, and Clear Logic LASICs can be
used for low cost, high volume production.
Clear Logics innovative laser ASIC technology eliminates NRE
costs, test vector development, ordering minimums and long lead
times. No re-simulation or re-layout is required, as the device is
engineered using a cell-based, PLD-like architecture. Clear
Logics TestCell technology ensures complete test coverage
through the use of specialized testing modes which are
transparent to the user.
The Clear Logic CL8000 Laser-Configured ASIC family is based
upon a large array of logic elements. Each logic element contains
a configurable look up table for combinatorial functions and a
register for sequential operations. A group of eight logic
elements forms a block. Laser-configured metal fuses implement
logical functions and control signal routing
Laser configuration provides reduced cost and enhanced
performance. These inherent performance benefits include
extremely consistent propagation delays, reduced power
consumption, and improved immunity to noise and upset events.
Clear Logics CL8000 LASIC
family is compatible with all six
configuration modes defined for the FLEX
8000 product family.
These configuration modes include the following:
u
Active Serial
u
Active Parallel Up
u
Active Parallel Down
u
Passive Parallel Synchronous
u
