SoC designers can now capture their design ideas with high-level languages like C and SystemC, then synthesize those abstractions down into RTL code or gates, however in the end the physical IC is implemented using cell libraries made up of transistors. Circuit designers use simulation tools like SPICE on these transistor-level… Read More
Spice circuit simulation remains the backbone of IC design validation. Digital cell library developers rely upon Spice for circuit characterization, to provide the data for Liberty models. Memory IP designers utilize additional Spice features to perform statistical sampling. Analog and I/O interface designers extend these… Read More
SPICE simulation is the workhorse tool for custom circuit timing validation and electrical analysis. As the complexity of blocks and macros has increased in advanced process nodes — especially with post-layout extraction parasitic elements annotated to the circuit netlist — the model size and simulation throughput… Read More
Working at Intel as a circuit designer I clearly remember how there were three distinct groups: Process Development, CAD and Circuit Design. Each of the groups sat in a different part of the building in Aloha Oregon, we had different job titles, different degrees, spoke with different acronyms and yet we all had to work together … Read More
Not only are foundries continuing to introduce processes at new advanced nodes, they are frequently updating or adding processes at existing nodes. There are many examples that illustrate this well. TSMC now has 16FF, 16FF+ and now 16FFC. They are also announcing 10nm and 7nm processes. In addition, they are going back to older… Read More
An SoC can have a collection of multiple blocks and IPs from different sources integrated together along with several other analog and digital components within a native environment. The IPs can be at different levels of abstractions; their RTL descriptions can be in different languages such as Verilog, VHDL, or SystemVerilog.… Read More
When technology advances, complexities increase and data size becomes unmanageable. Fresh thinking and a new environment for automation are needed to provide the required increase in productivity. Specifically in case of circuit simulation of advanced-node analog designs, where precision is paramount and a large number… Read More
About 35 years ago the first commercial SPICE circuit simulators emerged and they were quickly put to work helping circuit designers predict the timing and power of 6um NMOS designs. Then we had to limit our circuit simulations to just hundreds of transistors and interconnect elements to fit into the RAM and complete simulation… Read More
With the industry abuzz about the Apple purchase of a Maxim Integrated fab as a potential R&D facility for MEMS design, it begs the question: is creating a MEMS device that easy?
MEMS technology is approaching the same fork in the road where digital design encountered LSI four decades earlier. … Read More
“All models are wrong, some are useful.” This remark is attributed to the statistician George Box who used it as the section heading in a paper published in 1976.
Just for fun I looked up a few semiconductor statistics from 1976. Total capital spending was $238M in Japan and $306M in US and…that’s it, there was nobody else back then … Read More
