Date Rate Calculation || Verilog Coding Techniques Part 16 #allaboutvlsi #vlsi
The video walks through a Verilog‑style calculation of data rates for two simple modules. Module A sends four bits on each rising clock edge at a 100 MHz frequency, while Module B receives the parallel data and converts it to a serial stream using a PISO shift register. At 100 MHz the clock generates 100 × 10⁶ cycles per second. Multiplying by four bits per cycle gives Module A a throughput of 400 Mbits/s. When the same clock drives Module B, the PISO outputs only one bit per cycle, reducing the effective data rate to 100 Mbits/s. The presenter emphasizes the arithmetic: “time into frequency” yields cycles, and “cycles × bits per cycle” yields bit rate. The example illustrates how a parallel‑to‑serial conversion can slash bandwidth by a factor of four, even when clock speeds remain identical. For hardware designers, this stark contrast underscores the need to consider serialization overhead when sizing interfaces, selecting clock rates, or planning system‑level bandwidth. Choosing higher‑frequency clocks, wider parallel buses, or more efficient serializers becomes essential for meeting performance targets.
Decoder Based RAM Design in Verilog | SystemVerilog Testbench Series Day 2
The video walks through a Verilog implementation of a decoder‑based RAM module, the second installment of a SystemVerilog testbench series. It outlines the architecture of a 128‑byte memory organized as four 32‑byte blocks, each accessed via a 7‑bit address where...
Introduction to System Verilog Testbench || Decoder Based RAM Verification Part - 1 ||
The video walks through building a SystemVerilog testbench to verify a decoder‑based RAM, using a 16‑location, 8‑bit example. It first distinguishes a SystemVerilog testbench from a plain Verilog environment and outlines the verification plan that serves as the blueprint. It details...
