| * ### IOSAV memory controller interface poking state machine notes ### |
| * |
| * IOSAV brings batch processing to memory training algorithms. |
| * |
| * The hardware is capable of executing a sequence of DRAM commands, |
| * which can be composed of up to four sub-sequences. |
| * |
| * A sub-sequence (from now on, subseq) consists of executing the same |
| * DRAM command for a configurable number of times, with adjustable |
| * delay between the commands, as well as an address auto-increment |
| * value, which is added after a given number of command executions. |
| * |
| * There are four groups of registers in MCHBAR, one for each subseq. |
| * When firing up IOSAV, one needs to specify the number of subseqs it |
| * should use. |
| * |
| * The macros for these registers can take some integer parameters. |
| * Valid values are: |
| * channel: 0..1 or 3 to broadcast to all channels. |
| * index: 0..3 |
| * lane: 0..8 |
| * |
| * These ranges are inclusive: both upper and lower bounds are valid. |
| * |
| * |
| * |
| * ### Register descriptions ### |
| * |
| * IOSAV_n_SP_CMD_ADDR_ch(channel, index) |
| * Configures the row/column, bank and rank addresses. When a subseq |
| * begins to execute, the address fields define the address of the |
| * first command in the subseq. The address is updated after each |
| * command as configured in the "IOSAV_n_ADDR_UPDATE" registers, |
| * and the updated address is then written back into this register. |
| * |
| * Bitfields: |
| * [15..0] Row / Column Address. Defines the ADDR pins when |
| * issuing a DRAM command. |
| * |
| * [18..16] The number of valid row bits is this value, plus 10. |
| * Note: Value 1 is not implemented. |
| * Value 7 is unsupported, and thus reserved. |
| * |
| * [22..20] Bank select. |
| * [25..24] Rank select. It is later referred to as "ranksel". |
| * |
| * IOSAV_n_ADDR_UPDATE_ch(channel, index) |
| * How the address updates after executing a command in the subseq. |
| * |
| * Bitfields: |
| * [0] Increment row/column address by 1. |
| * [1] Increment row/column address by 8. |
| * [2] Increment bank select by 1. |
| * [4..3] Increment rank select by 1, 2 or 3. |
| * [9..5] Known as "addr_wrap", it limits the address increments. |
| * Address bits will wrap around the [addr_wrap..0] range. |
| * |
| * [11..10] LFSR update: |
| * 00: Do not use the LFSR function. |
| * 01: Undefined, treat as Reserved. |
| * 10: Apply LFSR on the [addr_wrap..0] bit range. |
| * 11: Apply LFSR on the [addr_wrap..3] bit range. |
| * |
| * [15..12] Update rate. The number of command runs between address updates. For example: |
| * 0: Update every command run. |
| * 1: Update every second command run. That is, half of the command rate. |
| * N: Update after N command runs without updates. |
| * |
| * [17..16] LFSR behavior on the deselect cycles (when no subseq command is issued): |
| * 0: No change w.r.t. the last issued command. |
| * 1: LFSR XORs with address & command (excluding CS), but does not update. |
| * 2: LFSR XORs with address & command (excluding CS), and updates. |
| * |
| * IOSAV_n_SP_CMD_CTRL_ch(channel, index) |
| * Configures how the DRAM command lines will be driven in each |
| * command of the subseq. |
| * |
| * Bitfields: |
| * [0] !RAS signal (as driven electrically). |
| * [1] !CAS signal (as driven electrically). |
| * [2] !WE signal (as driven electrically). |
| * |
| * [4] CKE, for DIMM 0 Rank 0. |
| * [5] CKE, for DIMM 0 Rank 1. |
| * [6] CKE, for DIMM 1 Rank 0. |
| * [7] CKE, for DIMM 1 Rank 1. |
| * [11..8] ODT, per DIMM & Rank (same encoding as CKE). |
| * [15..12] Chip select, per DIMM and Rank. It works as follows: |
| * |
| * entity CS_BLOCK is |
| * port ( |
| * MODE : in std_logic; -- Mode select at [16] |
| * RANKSEL : in std_logic_vector(0 to 3); -- Decoded "ranksel" value |
| * CS_CTL : in std_logic_vector(0 to 3); -- Chip select control at [15..12] |
| * CS_Q : out std_logic_vector(0 to 3) -- CS signals |
| * ); |
| * end entity CS_BLOCK; |
| * |
| * architecture RTL of CS_BLOCK is |
| * begin |
| * if MODE = '1' then |
| * CS_Q <= not RANKSEL and CS_CTL; |
| * else |
| * CS_Q <= CS_CTL; |
| * end if; |
| * end architecture RTL; |
| * |
| * [16] Chip Select mode control. |
| * [17] Auto Precharge. Only valid when using 10 row bits! |
| * |
| * IOSAV_n_SUBSEQ_CTRL_ch(channel, index) |
| * The parameters of the subseq: number of repetitions of the command, |
| * the delay between command executions, wait cycles after completing |
| * this subseq and before the next one, and the data direction of the |
| * command (read, write, neither, or both read and write). |
| * |
| * Bitfields: |
| * [8..0] Number of repetitions of the DRAM command in this subseq. |
| * [14..10] Number of DCLK cycles to wait between two successive DRAM commands. |
| * [24..16] Number of DCLK cycles to idle after this subseq and before the next subseq. |
| * [27..26] The direction of the data: |
| * 00: None (non-data command) |
| * 01: Read |
| * 10: Write |
| * 11: Read & Write |
| * |
| * IOSAV_n_ADDRESS_LFSR_ch(channel, index) |
| * 23-bit LFSR state. It is written into the LFSR when the subseq is |
| * loaded, and then read back from the LFSR when the subseq is done. |
| * |
| * Bitfields: |
| * [22..0] LFSR state. |
| * |
| * IOSAV_SEQ_CTL_ch(channel) |
| * IOSAV full sequence settings: number of subseqs, iterations, stop |
| * on error, maintenance cycles... |
| * |
| * Bitfields: |
| * [7..0] Number of full sequence executions. When this field becomes non-zero, then the |
| * sequence starts running immediately. This value is decremented after completing |
| * a full sequence iteration. When it is zero, the sequence is done. No decrement |
| * is done if this field is set to 0xff. This is the "infinite repeat" mode, and |
| * it is manually aborted by clearing this field. |
| * |
| * [16..8] Number of wait cycles after each sequence iteration. This wait's purpose is to |
| * allow performing maintenance in infinite loops. When non-zero, RCOMP, refresh |
| * and ZQXS operations can take place. |
| * |
| * [17] Stop-on-error mode: Whether to stop sequence execution when an error occurs. |
| * [19..18] Number of subseqs. The programmed value is the index of the last valid subseq. |
| * [20] If set, keep refresh disabled until the next sequence execution. |
| * DANGER: Refresh must be re-enabled within the (9 * tREFI) period! |
| * |
| * [22] If set, sequence execution will not prevent refresh. This cannot be set when |
| * bit [20] is also set, or was set on the previous sequence. This bit exists so |
| * that the sequence machine can be used as a timer without affecting the memory. |
| * |
| * [23] If set, an output pin is asserted on the first detected error. This output can |
| * be used as a trigger for an oscilloscope or a logic analyzer, which is pretty |
| * useful for debugging (if you have the equipment and know where this pin is). |
| * |
| * IOSAV_DATA_CTL_ch(channel) |
| * Data-related controls in IOSAV mode. |
| * |
| * Bitfields: |
| * [7..0] WDB (Write Data Buffer) pattern length: [7..0] = (length / 8) - 1; |
| * [15..8] WDB read pointer. Points at the data used for IOSAV write transactions. |
| * [23..16] Comparison pointer. Used to compare data from IOSAV read transactions. |
| * [24] If set, increment pointers only when micro-breakpoint is active. |
| * |
| * IOSAV_STATUS_ch(channel) |
| * Provides feedback on the state of the IOSAV sequence machine. |
| * Should be polled after submitting an IOSAV sequence for execution. |
| * |
| * Bitfields: |
| * [0] IDLE: IOSAV is sleeping. |
| * [1] BUSY: IOSAV is running a sequence. |
| * [2] DONE: IOSAV has completed a sequence. |
| * [3] ERROR: IOSAV detected an error and stopped on it, when using Stop-on-error. |
| * [4] PANIC: The refresh machine issued a Panic Refresh, and IOSAV was aborted. |
| * [5] RCOMP: RComp failure. Unused, consider Reserved. |
| * [6] Cleared with a new sequence, and set when done and refresh counter is drained. |
