Keysight Technologies Inc of Santa Rosa, CA, USA has announced the latest release of its GoldenGate simulation, analysis and verification software for large-scale RFIC circuit design. Keysight EEsof EDA (which supplies electronic design automation software for microwave, RF, high-frequency, high-speed digital, RF system, electronic system level, circuit, 3D electromagnetic, physical design and device-modeling applications) says that GoldenGate 2015.01 offers new and enhanced capabilities designed to improve productivity and efficiency for silicon RFIC designers.
Enhancements to GoldenGate’s simulator include Fast Envelope 3 support for envelope tracking modulation applications and support for multiple, non-harmonically-related frequency dividers. Support for the frequency dividers enables designers to more accurately predict receiver crosstalk (common in LTE-A Carrier Aggregation simulation). GoldenGate 2015.01 also features a new multi-threaded sparse matrix solver that enables 10-50% faster transient simulations, it is reckoned.
Additional improvements available in GoldenGate 2015.01 include the following:
faster crystal oscillator startup performance (five times faster out of the box, with a settled solution time of less than 20 periods versus greater than 10,000 for a full transient analysis); X-parameter simulation and data file improvements; improved Envelope Transient Noise analysis efficiency (up to a 1.5 times speed-up in envelope tracking noise); improved multi-threading and refactoring for harmonic balance noise (up to a 2.5 times speedup); and improved oscillator analysis performance (up to four times faster on the ring oscillator plus a divide by 32 circuit).
Additionally, GoldenGate 2015 enables designers to access the GoldenGate simulator from ADS by using GoldenGate-in-ADS and the new ADS RFIC cockpit (available in ADS 2015).
