 However, others such as P. L. Gupta and I. K. Sarma have disputed this identification, arguing that the Kotilingala coins belonged to a later ruler with a similar or same name.P.V.P.Sastry, who first discovered these coins and attributed them to Simuka in 1978, also changed his view and later stated that Chimuka or Chhimuka of Kotilingala was not same as the Simuka mentioned in Naneghat inscription.
