Seoul, South Korea, Jun. 16, 2023 – Baum Design Systems today launched the latest version of its SoC power analysis solutions PowerWurzel, Power Spion, and PowerBaum. Baum will showcase the products in Booth #1550 at the Design Automation Conference (DAC), held from Jul 10th to 14th at the Moscone Convention Center, San Francisco, CA, USA.

The Latest Version of PowerBaum

PowerBaum automatically generates power models from design sources and characterizes gate-level behavior to achieve very high accuracy. The power models run in higher abstraction environments, such as RTL/ESL simulation and hardware emulation to achieve orders of magnitude performance improvement compared to competing solutions in the market.
The new release supports power analysis with FSDB files generated in a hardware emulation. “Baum power models can accurately analyze power consumption considering glitches with emulator-generated FSDB files,” said Joonhwan Yi and Youngsoo Shin, Baum’s CEO. “Combining implementation-accurate Baum power models with hardware emulation creates an ideal solution for identifying and analyzing power problems under real operating conditions of large systems.” Users have seen over 1,000 times speed-up compared to competing power analysis solutions when PowerBaum is used together with hardware emulation.
The latest version supports a new feature of “Power Equation”, which is a much simplified power model. The equation can be tailored for HW power monitor implementation.

The Introduction of PowerSpion

Baum debuts a new product named PowerSpion. It reads in RTL Verilog source together with FSDB, and reports clock gating efficiency and offers power optimization guidelines. Clock gating efficiency includes CGE (clock gating efficiency), the percentage of cycles when each flop or register is gated; OCGR (operational clock gating ratio), the percentage of flops that are gated cycle by cyles (in a waveform); CGEE (clock gating enable efficiency), the percentage of cycles when each flop is actually gated over the ideal cycles when flop can be gated; and CGR (clock gating ratio), the percentage of flops that are controlled by ICG (integrated clock gating) cells. These reports are very useful while RTL is designed or debugged with clock gating implementation.
PowerSpion also offers a few power optimization guidelines. These include detection of RTL power inefficiency, e.g. constant clock gating enable signals, cascaded ICGs driven by the same enable signals, floating clock, memory macros without clock gating, etc.

The PowerWurzel

PowerWurzel is Baum’s gate-level power analysis solution. It can be integrated with PowerBaum (while power model is generated), or can be used as a stand-alone product. It can read in RTL FSDB as well as standard gate-level FSDB; the conversion of RTL to gate-level FSDB is performed internally before actual power analysis is performed on the netlist. The conversion itself can be used as a useful function because extraction of gate-level FSDB through simulation is an expensive process.
The latest PowerWurzel supports clock mesh as well as standard clock tree; power analysis at multiple voltage-temperature corners is another unique feature.
Furiosa AI, a fabless semiconductor company, used Baum’s power analysis suite to lower both peak power and average power consumption of their AI chip, Warboy, and plans to continue applying it in the designs of next generation chips. Recently, LXSemicon, one of the largest global display IC companies, adopted PowerBaum in developing their digital driver ICs (DDIs). ASICLAND, the only TSMC VCA in Korea, includes PowerBaum in the design process to provide RTL level power analysis service of customer design.
