4.1.2. RAM: 1-PORT Intel® FPGA IP Parameters
Parameter | Legal Values | Description | |
---|---|---|---|
Parameter Settings: Widths/Blk Type/Clks | |||
How wide should the ‘q’ output bus be? | — | Specifies the width of the ‘q’ output bus. | |
How many words of memory? | — | Specifies the number of bit words. | |
What should the memory block type be? |
|
Specifies the memory block type. The types of memory block that are available for selection depends on your target device. | |
Set the maximum block depth to |
|
Specifies the maximum block depth in words. | |
How should the memory be implemented? |
|
Specifies the logic cell implementation method.
|
|
Which clocking method would you like to use? |
|
Specifies the clocking method to use.
|
|
Parameter Settings: Regs/Clken/Byte Enable/Aclrs | |||
Which ports should be registered?
The following options are available:
|
On/Off | Specifies whether to register the input and output ports. | |
Create one clock enable signal for each clock signal.
Note: All registered ports are controlled by the enable signal(s).
|
On/Off | Specifies whether to turn on the option to create one clock enable signal for each clock signal. | |
More Options | Use clock enable for port A input registers | On/Off | Specifies whether to use clock enable for port A input registers. |
Use clock enable for port A output registers | On/Off | Specifies whether to use clock enable for port A output registers. | |
Create an ‘addressstall_a’ input port. | On/Off | Specifies whether to create an addressstall_a input port. You can create this port to act as an extra active low clock enable input for the address registers. | |
Create byte enable for port A | On/Off | Specifies whether to create a byte enable for port A. Turn on this option if you want to mask the input data so that only specific bytes, nibbles, or bits of data are written. To enable byte enable for port A and port B, the data width ratio has to be 1 or 2 for the RAM: 1-PORT and RAM: 2-PORT Intel® FPGA IPs. |
|
What is the width of a byte for byte enables? |
|
Specifies the byte width of the byte enable port. The width of the data input port must be divisible by the byte size. | |
Create an ‘aclr’ asynchronous clear for the registered ports. ‘q’ port |
On/Off | Specifies whether the registered ports are affected by an asynchronous clear port. | |
Create an ‘sclr’ synchronous clear for the registered ports. ‘q’ port |
On/Off | Specifies whether the registered ports are affected by a synchronous clear port. | |
Create a ‘rden’ read enable signal | On/Off | Turn on if you want to create a read enable signal. | |
Parameter Settings: Read During Write Option | |||
What should the ‘q’ output be when reading from a memory location being written to? |
|
Specifies the output behavior when read-during-write occurs. Don’t Care—The RAM outputs “don't care” or “unknown” values for read-during-write operation. Old Data—The RAM outputs reflect the old data at that address before the write operation proceeds. |
|
Get x’s for write masked bytes instead of old data when byte enable is used | On/Off | Turn on this option to obtain ‘X’ on the masked byte. | |
Parameter Settings: Mem Init | |||
Do you want to specify the initial content of the memory? |
|
Specifies the initial content of the memory. To initialize the memory to zero, select No, leave it blank. To use a memory initialization file (.mif) or a hexadecimal (Altera-format) file (.hex), select Yes, use this file for the memory content data. |
|
Initialize memory content data to XX..X on power-up in simulation | On/Off | — | |
Implement clock-enable circuitry for use in a partial reconfiguration region | On/Off | Specifies whether to implement clock-enable circuitry for use in a partial reconfiguration region. | |
Allow In-System Memory Content Editor to capture and update content independently of the system clock | On/Off | Specifies whether to allow In-System Memory Content Editor to capture and update content independently of the system clock. | |
The ‘Instance ID’ of this RAM is | NONE | Specifies the RAM ID. | |
Parameter Settings: Performance Optimization | |||
Enable Force To Zero | On/Off | Specifies whether to set the output to zero when you deassert the read enable signal. Enabling this feature helps improve the glue logic performance when the selected memory depth is larger than a single memory block. |
