How many firms are there in Bangladesh which are engaged in chip designing?
Oh I'd venture a guess, about a half dozen.
The expertise is highly specialized and not as commonly found on our shores as it is in (say) the US or Western countries. People from Bangladesh (new engineers from BUET etc.) have to be trained in the skillsets. This training and skill cannot be gained in short order - will take decades. But it is doable.
Most of the companies are founded by ex-Silicon Valley Bangladeshi folks. Ulka Semi is one of the frontrunners.
The type of CAD software used in semiconductor chip design is called electronic design automation (EDA) tools, which include schematic capture, layout design, simulation, and verification functions. Examples include,
1. IBM's Automated Logic Diagram,
2. Calma's GDSII, and
3. Synopsys RedHawk-SC and Ansys products for power integrity and Multiphysics analysis.
Ulka Semi says it uses EDA tools in its chip design services, but it doesn’t publicly name the specific EDA vendors/products it runs.
Ulka Semi states that its engineers utilize "a diverse array of Electronic Design Automation (EDA) tools” for IC design, including physical design and optimization for PPA.
For IC design services - it says each engineer is “proficient in most of the latest EDA tools within their area of expertise.”
It also describes work in verification, DFT, foundry design services, and physical design flows (e.g., RTL/netlist to GDS2/handovers), which are typically EDA-tool-dependent.
As you can guess - highly, highly specialized tools.
