Hello Dear Readers, Today in this post, I will provide some deep insight into the Signal Electromigration (Signal EM): Violations, Examples, and Practical Fixes. 1. Introduction: As technology nodes shrink into the deep‑submicron and nanometer regime (7nm, 5nm, 3nm and beyond), electromigration (EM) has become a first‑order reliability concern—not only for power/ground (PG) networks but also for signal nets. Signal EM failures are often underestimated because signal currents are transient and bidirectional. However, with higher switching activity, tighter metal pitches, thinner wires, and aggressive timing closure, signal EM can cause latent or early‑life failures if not addressed properly. This article explains: What Signal EM is and how it differs from PG EM Typical Signal EM violation scenarios Detailed, practical examples Root causes behind each violation Proven solutions and best practices to fix and prevent Signal EM issues 2. What is Signal Electromigration: El...
Hello Dear Readers, Today in this post I will provide some basics to advanced ARM's assembly language practice QA I have used the Keil tool for code writing. Q-1). Perform subtraction of the numbers stored at memory location 0x4000 from the number stored at memory location 0x4004 and place the result in memory location 0x4008. Code: ; Program of the substraction area into, code, readonly entry mov r1, #0x4000 ldr r2,[r1] ldr r3,[r1, #4] sub r4,r3,r2 ; perform substraction operation str r4,[r1, #8] ; store the result at memory location 0x4008 end Output: Q-2). Write a program to check whether the number stored at the memory location is even or odd. Code: ; program for identity number is even or odd area prog2, code, readonly entry mov r1,#0x4000 ; data location ldr r2,[r1] tst r2,#1 ; anding with 0x01 will be updating status of flag register bne odd mov...
