MACH4-96

High-Performance EE CMOS Programmable Logic

Lattice Semiconductor 

VANTIS

The M4-96/96 has macrocells that can be configured as synchronous or asynchronous. This allows

designers to implement both synchronous and asynchronous logic together on the same device.

The two types of design can be mixed in any proportion, since the selection on each macrocell

affects only that macrocell.

Up to 20 product terms per macrocell can be assigned. It is possible to allocate some product terms

away from a macrocell without losing the use of that macrocell for logic generation.

The M4-96 macrocell provides either registered or combinatorial outputs with programmable

polarity. If a registered configuration is chosen, the register can be configured as D-type, T-type, J-

K, or S-R to help reduce the number of product terms used. The flip-flop can also be configured as

a latch. The register type decision can be made by the designer using software.

All macrocells can be connected to an I/O cell through the output switch matrix. The output switch

matrix makes it possible to make significant design changes while minimizing the risk of pinout

changes.

Vantis offers software design support for MACH devices through its own development system and

device fitters integrated into third-party CAE tools. Platform support extends across PCs, Sun and

HP workstations under advanced operating systems such as Windows 3.1, Windows 95 and NT,

SunOS and Solaris, and HPUX.

MACHXL® software is a complete development system for the PC, supporting Vantis’ MACH

devices. It supports design entry with Boolean and behavioral syntax, state machine syntax and

truth tables. Functional simulation and static timing analysis are also included in this easy-to-use

system. This development system includes high-performance device fitters for all MACH devices.

The same fitter technology included in MACHXL software is seamlessly incorporated into third-

party tools from leading CAE vendors such as Synario, Viewlogic, Mentor Graphics, Cadence and

MINC. Interface kits and MACHXL configurations are also available to support design entry and

verification with other leading vendors such as Synopsys, Exemplar, OrCAD, Synplicity and Model

Technology. These MACHXL configurations and interfaces accept EDIF 2.0.0 netlists, generate

JEDEC files for MACH devices, and create industry-standard SDF, VITAL-compliant VHDL and

Verilog output files for design simulation.

Vantis offers in-system programming support for MACH devices through its MACHPRO® software

enabling MACH device programmability through JTAG compliant ports and easy-to-use PC

interface. Additionally, MACHPRO generated vectors work seamlessly with HP3070, GenRad and

Teradyne testers to program MACH devices or test them for connectivity.

All MACH devices are supported by industry standard programmers available from a number of

vendors. These programmer vendors include Advin Systems, BP Microsystems, Data I/O

Corporation, Hi-Lo Systems, SMS GmbH, Stag House, and System General.
