This is our version of tetris, with "GUIDELINES" as an option. These will allow you to easily se where the pieces will fall, be highlighing the columns that the falling piece is at the given moment.

Since the original publication of Manual 74 in 1991, and the preceding
“GUIDELINES for Transmission Line Structural Loading” in 1984, the
understanding of structural loadings on transmission line structures has
broadened signifi cantly. However, improvements in computational capa-
bility have enabled the transmission line engineer to more easily deter-
mine structural loadings without properly understanding the parameters
that affect these loads. Many seasoned professionals have expressed
concern for the apparent lack of recent information on the topic of struc-
tural loadings as new engineers enter this industry. The Committee on
Electrical Transmission Structures is charged with the responsibility to
report, evaluate, and provide loading requirements of transmission struc-
tures. This task committee was therefore formed to update and revise the
1991 manual.
In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding GUIDELINES are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.
One of the most misunderstood constructs in the Verilog language is the nonblockingassignment. Even very experienced Verilog designers do not fully understand how nonblockingassignments are scheduled in an IEEE compliant Verilog simulator and do not understand whenand why nonblocking assignments should be used. This paper details how Verilog blocking andnonblocking assignments are scheduled, gives important coding GUIDELINES to infer correctsynthesizable logic and details coding styles to avoid Verilog simulation race conditions
Abstract: This application note presents an overview of the operational characteristics of accurate I²C real-time clocks (RTCs),including the DS3231, DS3231M, and DS3232. It focuses on general application GUIDELINES that facilitate use of device resources forpower management, I²C communication circuit configurations, and I²C characteristics relative to device power-up sequences andinitializations. Additional discussions on decoupling are provided to support developing strategies for mitigating power-supply pushingof device frequency.
Low power operation of electronic apparatus has becomeincreasingly desirable. Medical, remote data acquisition,power monitoring and other applications are good candidatesfor battery driven, low power operation. Micropoweranalog circuits for transducer-based signal conditioningpresent a special class of problems. Although micropowerICs are available, the interconnection of these devices toform a functioning micropower circuit requires care. (SeeBox Sections, “Some GUIDELINES for Micropower Designand an Example” and “Parasitic Effects of Test Equipmenton Micropower Circuits.”) In particular, trade-offs betweensignal levels and power dissipation become painful whenperformance in the 10-bit to 12-bit area is desirable.
Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsiderations and general recommendations for choosing a 0.4mm- or 0.5mm-pitch WLP for yourapplication.
