For more details about how to implement the desired behavior, read-during-write
behavior is controlled via the RAM MegaWizard Plug-In Manager refer to the
Megafunction User
You should select don’t care mode if you do not use old data mode. This increases the
flexibility in the type of memory block used, if you do not assign block type when
instantiating a memory block. You may also get potential performance gain by
selecting don’t care mode.
Figure 4–21
behavior for the old data mode. In don’t care mode, the old data shown in the figure is
simply replaced with “don’t cares”.
Mixed-port read-during-write using two different clocks in simple-dual port RAM
with old data output is supported via emulation. The Quartus II software takes two
memory blocks to implement the widest width mode.
M9K and M144K memory block outputs power up to zero (cleared), regardless of
whether the output registers are used or bypassed. MLABs power up to zero if output
registers are used and power up reading the memory contents if output registers are
not used. However, the actual RAM cells power up to an unknown state. Therefore,
after power-up, if an address is read before being written, the output from the read
operation is undefined because the contents are not initialized.
All memory blocks support initialization via .mif file. You can create .mif files in the
Quartus II software and specify their use with the RAM MegaWizard Plug-In
Manager when instantiating a memory in your design. Even if a memory is
pre-initialized (for example, by a .mif file), it still powers up with its outputs cleared.
For more information about .mif files, refer to the
