Effective-one-body (EOB) numerical-relativity (NR) waveform models forspin-aligned binary black holes (BBHs), known as the SEOBNR waveform models,are based on the EOB theoretical framework and NR simulations. SEOBNR modelshave played an important role in the LIGO scientific collaboration (LSC)gravitational wave (GW) data analysis for both signal search and parameterestimation. SEOBNR models for quasi-circular orbits have evolved throughversion 1 to version 4 by extending their validity domain and including more NRresults. Along another direction, we recently extended SEOBNRv1 model toSEOBNRE model which is valid for spin-aligned BBH coalescence along eccentricorbits. In this paper we validate this theoretical waveform model by comparingthem against the numerical relativity simulation bank, Simulating eXtremeSpacetimes (SXS) catalog. In total, 278 NR waveforms are investigated whichinclude binaries with large eccentricity; large spin and large mass ratio. OurSEOBNRE can model the NR waveforms quite well. The fitting factor for most ofthe 278 waveforms is larger than 99\%. It indicates that the SEOBNRE modelcould be used as template waveforms for eccentric spin-aligned BBH coalescence.
