Eldo Premier
Overview of Eldo Premier
Boosting performance over standard analog simulation can help in two ways. Critically
important simulations that require extremely long simulations times, sometimes measured in
days or weeks, can be reduced very significantly.
Together with the performance improvements for verification tasks, the additional simulation
power can be used to run many more corners or operating conditions, and thus verify a design or
analog IP block much more thoroughly. For example, it may become practical to verify an
entire temperature range or power-supply range instead of just the nominal point of the
specifications. This can dramatically improve the confidence in the design or IP before tape-out,
with the goal of eliminating silicon re-spins, and improving the final manufacturing yield.
Some of the features and benefits of the Eldo Premier simulator include:
• Raw performance improvement over Eldo Classic, on both single-core and multi-core
machines.
• Same golden accuracy as Eldo Classic.
• Much higher capacity (factor of 10) than Eldo Classic.
• Much better scalability of the multi-thread performance.
• Same device models and libraries as Eldo Classic.
• Same use model as Eldo Classic.
• Supports .EXTRACT, .MEAS, .STEP, .ALTER, and .CHECKSOA commands of Eldo
Classic.
• Supports RCC parasitic network reduction.
• Integrated in Questa ADMS for mixed-signal verification including VHDL/Verilog and
VHDL-AMS/Verilog-AMS descriptions, see “vasim -premier” in the Questa ADMS
Reference Manual.
Note
Eldo Premier is only supported on Linux platforms. It is not supported on Windows
platforms.
Target Applications
The Eldo Premier simulator targets applications that require CPU-intensive DC and transient
simulations, such as PLLs and DLLs, frequency synthesizers, delta-sigma converters, ADC/
DAC audio and video converters, automotive circuits, DC-DC converters, regulators, power
management circuits, memory critical paths analysis, and TFT/OLED panels.
The scope of applicability is the same as Eldo Classic because the algorithms do not presuppose
any particular structure within the simulated circuit. The much higher capacity of Eldo
Premier opens new possibilities in the field of memory (SRAM/DRAM) and TFT/OLED panel
