Designers on emerging process nodes must meet aggressive PPA and productivity goals. It essentially means efficient and intelligent
handling of 100s of millions of place-able instances, multiple levels of hierarchy, 1000s of hard macros, 100s of clocks, wide busses,
and 10s of modes and corners power domains and complex design constraints and process technology mandates.

Emphasis on Designer Productivity
IC Compiler II is architected from the ground up for speed and scalability. Its hierarchical data model consumes 2-3X less memory
than conventional tools, boosting the limits of capacity to 500M placeable instances and beyond. Adaptive abstraction and on-the-fly
data management minimize memory requirements and enable fast responsive data manipulation. Near-linear multi-core threadingof key infrastructural components and core algorithms such as database access and timing analysis speed up optimization at allphases of design. Patented, lossless compact modeling and independent R and C extraction allow handling more modes and corners(MCMM scenarios) with minimal runtime impact.
IC Compiler II has built-in Reference Methodology(RM) that ensures fast flow bring up. This RM Flow is Foundry Process/Design Typespecific to ensure a robust starting point and seamless bring up. IC Compiler II has direct access to the Golden PrimeTime delay
calculation engine to minimize ECO iterations.

IC Compiler II’s new data model enables designers to perform fast exploration and floorplanning with complex layout requirements.
IC Compiler II can create bus structures, handle designs with n-levels of physical hierarchy, and support Multiply Instantiated Blocks(MIBs) in addition to global route driven pin assignment/feedthrough flow, timing driven macro placement, MV area design planning.
A design data mismatch inferencing engine analyzes the quality of inputs and drives construct creation on the fly, delivering design
insights even with “incomplete” data early in the design cycle. Concurrent traversal of logical and physical data models enables
hierarchical Data-Flow Analysis (DFA) and fast interactive analysis through multi-level design hierarchies and MIBs. Data flow andfeedthrough paths highlighted in Figure 2 allow analysis and manipulation through n-levels of hierarchy to complete early design
exploration and prototyping.

Pipeline-register-planning shown in Figure 3, provides guidance for optimal placement to meet the stringent timing requirementsof high-performance designs. Interactive route editor integrated which is advanced node aware shown in Figure 4, allows intricate
editing and routing functions, including the creation of special signal routes, buses, etc.

Achieving Best Performance, Power, Area, and TAT
IC Compiler II features a new optimization framework built on global analytics. This Unified TNS Driven Optimization framework isshared with Design Compiler NXT synthesis to enable physically-aware synthesis, layer assignment, and route-based optimization
for improved PPA and TAT. Multi-Corner Multi-Mode (MCMM) and Multi-Voltage (MV) aware, level-based analytical algorithms
continuously optimize using parallel heuristic algorithms. Multi-factor costing functions deliver faster results on both broad andtargeted design goals. Concurrent PPA driven logic remapping, rewiring, and legalization interleaved with placement minimizes
congested logic, resulting in simple localized logic cones that maximize routability and QoR.

IC Compiler II minimizes leakage with fast and efficient cell-by-cell power selection across HVT, SVT and LVT cells and varying
channel lengths. Activity-driven power optimization uses VCD/ SAIF, net toggle rates, or probability functions to drive placement
decisions and minimize pin capacitances. Multi-bit register banking optimizes clock tree structures, reduces area, and net length,
while automatically managing clock, data, and scan chain connections.
Advanced modeling of congestion across all layers highlighted in Figure 4 provides accurate feedback throughput the flow fromdesign planning to post- route optimization.

IC Compiler II introduces a new Concurrent Clock and Data (CCD) analysis and optimization engine that is built-in to every flow step
resulting in meeting both aggressive performance and minimizing total power footprint. ARC-based CCD optimization performs clocktree traversal across all modes/corners in path-based fashion to ensure optimal delay budgeting.
Robust support for clock distribution enables virtually any clock style, including mesh, multi-source, or H-tree topologies. Advanced
analysis and debugging features perform accurate clock QoR analysis and debugging as highlighted in Figure 5.
