Foundation Express F2.1i: When will the "zero-one-hot" synthesis option be supported?


Keywords: Foundation, Express, synthesis, options, FSM, zero, one-hot

Urgency: Standard

General Description:
The standalone version of Synopsys Express which can be accessed through Foundation 1.5i has
an additional synthesis option regarding FSM encoding (zero-one-hot) which is not present when
the Express synthesis tool is used in a Foundation project.

Zero-one-hot is an encoding style similar to One-hot. This format requires N-1 flip flops to define N
unique states, where the reset state is defined by all zeros.


This option has been implemented in Foundation 2.1i. Select Synthesis -> Options to set this
encoding style (and then re-analyze your HDL source).
