    <p>I have a problem with a generate statement. I'm generating a pipeline architecture, the basic problem is that I need another counter or variable besides the for index:</p> <pre><code>architecture behav of blockPipelineCordic is constant total: integer := stepNumber + stepNumber/pipeStep; signal signVector: std_logic_vector( (stepNumber - 1) downto 0); signal lx: std_logic_vector( ((total + 1)*dataSize - 1) downto 0); signal ly: std_logic_vector( ((total + 1)*dataSize - 1) downto 0); signal signCounter: integer := stepNumber - 1; begin stepGen: for i in (total - 1) downto 0 generate begin signCounter &lt;= signCounter - 1 when ((total - i) mod (pipeStep + 1) /= 0) else signCounter; stepGen0: if( (total - i) mod (pipeStep + 1) /= 0 ) generate begin U1: entity work.cordicStep(behav) generic map ((totalStepNumber - 1) - i,dataSize) port map(signVector(signCounter),lx(((i+2)*dataSize-1) downto (i+1)*dataSize),ly(((i+2)*dataSize-1) downto (i+1)*dataSize),lx(((i+1)*dataSize-1) downto i*dataSize),ly(((i+1)*dataSize-1) downto i*dataSize)); end generate stepGen0; stepGen1: if( (total - i) mod (pipeStep + 1) = 0 ) generate begin U2: entity work.registerModule(behav) generic map (dataSize) port map(clk,lx(((i+2)*dataSize-1) downto (i+1)*dataSize),lx(((i+1)*dataSize-1) downto i*dataSize)); end generate stepGen1; stepGen2: if( (total - i) mod (pipeStep + 1) = 0 ) generate begin U3: entity work.registerModule(behav) generic map (dataSize) port map(clk,ly(((i+2)*dataSize-1) downto (i+1)*dataSize),ly(((i+1)*dataSize-1) downto i*dataSize)); end generate stepGen2; end generate stepGen; . . . </code></pre> <p>In the generation of the first structure I need to use a different index to signVector, I created a signal to be used as a counter (port map(signVector(signCounter),lx(((i+2)*dataSize-1) downto ) but it cannot be used as an index the error is: "Actual (indexed name) for formal "sub" is not a static signal name."</p> <p>Any help would be appreciated :), ty</p>

    1. COYour `signCounter` is assigned `total` times ! Remeber that all `<=` are **concurrent** assignments.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
