Modeling issue: L293 for unidirectional DC motor control

In my SimulIDE model, I'm trying to control water pumps with L293 drivers:

Modeling issue: L293 for unidirectional DC motor control  SimulIDE_model

According to the L293 manual (Table 2. Unidirectional DC Motor Control, page 11), I should be able to drive my PWM signal on the "EN" inputs while tying the "A" inputs high.

In the simulation I see an output voltage of 4.55V when the "EN" input is driven low and the motors are in motion, when there shouldn't be any current running through them.

Thanks for reporting.
Solved at Rev 1673.

In the meanwhile you can just control the input lines instead of enable.
