Memory design EDA tools

Every SRAM block inside an Indian-designed chip is compiled by software from one of three foreign vendors. As of 2026, India relies entirely on imported tools from Synopsys, Cadence and Siemens EDA for memory design, with no known indigenous programme to build an alternative.

Memory design EDA tools are a narrow, specialised corner of an already concentrated industry. General digital design tools do not suffice: memory companies such as Samsung, SK Hynix, Micron and Kioxia use distinct tools for DRAM, NAND and HBM design. At the heart of the discipline sits the memory compiler — software that generates memory cells for a given process technology. Synopsys memory compilers, for example, span foundry nodes from 250 nanometres down to 2 nanometres. Producing that breadth means optimising simultaneously for power, performance and area, the trade-off engineers call PPA, across device structures that change with every new process generation.

The global market is unusually thin. Synopsys, Cadence, Siemens EDA and Ansys together account for a large share of it. Only two nations — the United States and China — are counted among the possessors of memory design EDA capability. China's Huada Empyrean has emerged as a domestic EDA vendor covering analog, mixed-signal and digital SoC design, illustrating that the oligopoly is not immutable.

India's semiconductor design ecosystem is real but pointed elsewhere. It excels in networking, microprocessors, analog design and memory subsystems, and the government's ChipIN Centre, run by C-DAC, has democratised access to advanced EDA tools for about one lakh engineers and students across 400 organisations. That access is to imported tools. It builds designers, not the tools they design with.

The gap persists because the tool sits atop a deep stack. A memory compiler is only the visible layer above EDA infrastructure and licensing, process design kits that translate designs to a specific foundry, TCAD and circuit simulation that model cell behaviour, and physical verification tools that check layout. India is producing several of these foundational capabilities but its PDK ecosystem is still emerging — and a memory tool is only as current as the process nodes its PDKs support. High EDA licensing costs are already cited as a barrier for Indian design houses; building the tools rather than renting them is a further order of difficulty.

Closing the gap would mean maturing the foundational layers first — PDKs above all — then targeting the memory compiler as a specialised application built on infrastructure India already produces. It is a climb of many stages, and India has begun only the lowest.
