  We study realization of the democratic form of Yukawa matrices by infrared
fixed points. We investigate renormalization-group flows of Yukawa couplings in
models with a single Yukawa matrix for three families, and up and down-sector
Yukawa matrices. It is found that each model has its certain pattern of
renormalization-group flows of Yukawa matrices. We apply them to the charged
lepton sector and quark sector, and show that realistic results for the second
and third families are obtained with natural initial conditions, e.g.
$(V_{MNS})_{23} \sim 2/\sqrt{6}$, $m_s/m_b \sim V_{cb} \sim m_{\mu}/m_\tau$ and
$m_c/m_t \sim (m_s/m_b)^{3/2}$. We also study corresponding A-terms. The
A-terms approach toward the universal form with no physical CP-violating phase.
Thus, constraints due to various neutral flavor changing processes except for
$\mu \to e \gamma$ are found to be satisfied by this dynamics. In order to
suppress the electric dipole moments as well as $\mu \to e \gamma$
sufficiently, more alignment of the A-terms with some reason is required.
