It is interesting to note that in these early days Calma developed a format to represent IC layouts called GDS, named after its product, Graphic Design System. The GDS II version of this format continued to be used as the de-facto format to communicate IC layout information for decades. ...
A Graphic Database System (GDSII) file, which is a binary file format that encodes plane geometric objects, text labels, and other information related to the physical layout, is the outcome of the physical layout process. The following are the steps involved in the physical layout: ...
In the pre-EDA days, these companies also wrote the software needed to design and manufacture custom chips – everything from simulation and layout to fracturing those layouts into trapezoids to make photomasks. Chapter One lasted from about the 1950s to the early 1980s. Chapter Two: The ...
Proficiency in Design and EDA Tools:VLSI design thrives on advanced EDA tool expertise, with mastery over tools for logic synthesis, simulation, and layout optimization. From schematic capture to physical layout, VLSI engineers skillfully navigate EDA platforms to translate designs into functional silicon...
Here is another Samsung mystery. Why is Samsung VLSI counted as part of Samsung Foundry revenue? That would be like counting Intel chip revenue as Intel Foundry revenue making them the #1 foundry in the world! View attachment 198 Some interesting info: 1. From Samsung 2020Q2 PR news: a....
What is Skipper? Well, it seems it’s a penguin in the movie Madagascar. And one of Barbie’s sisters. Who knew? But for Semiwiki readers it’s an integrated chip finishing platform from ICScape. Skipper can read in full-chip layout extremely fast, examine it and manipulate it in variou...
doing so is much more complicated a process with an SoC. In fact, it is near impossible to make changes to a system on chip once it has been manufactured, meaning if it is damaged or needs to be updated, you are better off making a new one rather than even attempting to repair or ...
From toy keyboards to performance-grade pianos, synthesizers, and drum sets, to name a few, instruments that once would have been finely crafted wood and metal can today find their voices in CPUs, memory, and data converters. This does not mean craftsmanship is dead. There is as much skill...
Engineers start by defining the task and designing a circuit layout tailored to it. This design is then etched onto asilicon wafer, creating a chip optimized for that specific job. For example, an ASIC fordata encryptionis built to handle encryption quickly and with minimal power use. ...
With a bitplane-layout (like the 16 color VGA-modes) one would have to use the bit-shift-opcodes (ROR/ROL). That’s 6 cycles per byte (8 pixel). So at the said resolution that would sum up to 1.2 million cycles per plane. 16 colors=4 planes=5 million cycles just for the scroll...
