VMIVME-7586 Error Notiﬁcation

Because of a recently discovered design ﬂaw in the VIC64 (Cypress

Semiconductor) used to implement the VMEbus interface on the

VMIVME-7586, VMIC warns users that a malfunction may occur. The

following paragraphs below provide information from Cypress concerning

the conditions that must be present to cause this malfunction.

Cypress Erratum:

The following paragraphs came directly from the 6/13/97 Cypress Erratum (Reference No.95):

Lword and A7-A1 are driven on the VMEbus by a VIC64 slave that is not the addressed slave to the D64

transaction in progress thus corrupting the data of the transaction.The following condition must be met to see

this failure:

1. Deﬁning this misbehaving VIC64 as the “failing slave” and the transaction in which the failure is

noted the “current transaction.”

2. The failing slave was the addressed slave to the transaction immediately preceding the current

transaction.We deﬁne this transaction to be the “preceding transaction.”

3. The preceding transaction was a D64 slave read from the failing slave.

4. The current transaction must be a D64 transaction.

5. The preceding transaction exhibits a local “read ahead” cycle which extends (local PAS+ signal is

asserted) beyond the address broadcast phase (ﬁrst VMEbus DS1/0 deassertion after AS*

assertion) of the current transaction.

Work around, Hardware:

PAS* must be deasserted before DSB (later deassertion of either DS1/0) of the address broadcast cycle of

the current transaction deasserts.

VMIC’s Response:

These conditions may arise if:

1. You have more than one device that may be slave to 64-bit block transfers and at least one has a

VIC64 chip.

2. Block transfer master(s) can reassert AS* and execute a BLT 64 Address Broadcast quickly (less

than about 100 ns AS* hightime).

The VIC64 as used on the VMIVME-7586 does not cause trouble during Master Mode. In other words, the

VMIVME-7586 can safely do master BLT 64 transactions under all conditions.The described malfunction only

occurs when the VIC64 is a BLT 64

slave

(read

from/by

master)

and

the slave transaction is rapidly followed

another

BLT 64 slave transaction

another slave.

SAFETY SUMMARY

THE FOLLOWING GENERAL SAFETY PRECAUTIONS MUST BE OBSERVED DURING ALL PHASES

OF THE OPERATION, SERVICE, AND REPAIR OF THIS PRODUCT. FAILURE TO COMPLY WITH

THESE PRECAUTIONS OR WITH SPECIFIC WARNINGS ELSEWHERE IN THIS MANUAL VIOLATES

SAFETY STANDARDS OF DESIGN, MANUFACTURE, AND INTENDED USE OFTHIS PRODUCT. VME

MICROSYSTEMS INTERNATIONAL CORPORATION ASSUMES NO LIABILITY FOR THE

CUSTOMER'S FAILURETO COMPLY WITHTHESE REQUIREMENTS.

GROUNDTHE SYSTEM

To minimize shock hazard, the chassis and system cabinet must be connected to an electrical

ground. A three-conductor AC power cable should be used. The power cable must either be

plugged into an approved three-contact electrical outlet or used with a three-contact to

two-contact adapter with the grounding wire (green) ﬁrmly connected to an electrical ground

(safety ground) at the power outlet.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

Do not operate the system in the presence of ﬂammable gases or fumes. Operation of any

electrical system in such an environment constitutes a deﬁnite safety hazard.

KEEP AWAY FROM LIVE CIRCUITS

Operating personnel must not remove product covers. Component replacement and internal

adjustments must be made by qualiﬁed maintenance personnel. Do not replace components

with power cable connected. Under certain conditions, dangerous voltages may exist even with

the power cable removed. To avoid injuries, always disconnect power and discharge circuits

before touching them.

DO NOT SERVICE OR ADJUST ALONE

Do not attempt internal service or adjustment unless another person, capable of rendering ﬁrst

aid and resuscitation, is present.

DO NOT SUBSTITUTE PARTS OR MODIFY SYSTEM

Because of the danger of introducing additional hazards, do not install substitute parts or perform

any unauthorized modiﬁcation to the product. Return the product to VME Microsystems

International Corporation for service and repair to ensure that safety features are maintained.

DANGEROUS PROCEDUREWARNINGS

Warnings, such as the example below, precede only potentially dangerous procedures

throughout this manual. Instructions contained in the warnings must be followed.

DANGEROUS VOLTAGES, CAPABLE OF CAUSING DEATH, ARE PRESENT IN THIS SYSTEM. USE

EXTREME CAUTIONWHEN HANDLING,TESTING, AND ADJUSTING.

NOTE:

WARNING

GENERAL DEFINITIONS OF SAFETY SYMBOLS USED IN THIS

MANUAL

Instruction manual symbol: the product is marked with this symbol when it is

necessary for the user to refer to the instruction manual in order to protect against

damage to the system.

Indicates dangerous voltage (terminals fed from the interior by voltage exceeding

1000 volts are so marked).

Protective conductor terminal. For protection against electrical shock in case of a

fault. Used with ﬁeld wiring terminals to indicate the terminal which must be

connected to ground before operating equipment.

Low-noise or noiseless, clean ground (earth) terminal. Used for a signal common,

as well as providing protection against electrical shock in case of a fault. Before

operating the equipment, terminal marked with this symbol must be connected to

ground in the manner described in the installation (operation) manual.

Frame or chassis terminal. A connection to the frame (chassis) of the equipment

which normally includes all exposed metal structures.

Alternating current (power line).

Direct current (power line).

Alternating or direct current (power line).

The WARNING sign denotes a hazard. It calls attention to a procedure, a

practice, a condition, or the like, which, if not correctly performed or adhered to,

could result in injury or death to personnel.

The CAUTION sign denotes a hazard. It calls attention to an operating procedure,

a practice, a condition, or the like, which, if not correctly performed or adhered to,

could result in damage to or destruction of part or all of the system.

The NOTE sign denotes important information. It calls attention to a procedure, a

practice, a condition or the like, which is essential to highlight.
